Cabinet Tambour Shutter

  • Q. What does tambour mean?

    A. Well, it is defined by as: Furniture - a flexible shutter used as a desk top or in place of a door, composed of a number of closely set wood strips attached to a piece of cloth, the whole sliding in grooves along the sides or at the top and bottom. If you use aluminum in place of the "wood strips" that sums it up quite well.

  • Q. What is the maximum width for Cabinet Tambour Shutter?

    A. Depending on the model, it could go as wide as 4 feet.

  • Q. What is the maximum height for Cabinet Tambour Shutter?

    A. There is no standard height. You should always keep in mind this type of door has no counterbalance and therefore total weight is an issue and it can come down fast if the user does not control it.

  • Q. Can Cabinet Tambour Shutters be motor operated?

    A. Never. If you do need a motorized shutter you should look at the Mini Roll-Up line.

  • Q. Is there any other method of operating a Cabinet Tambour Shutter besides manual push up?

    A. No. Cabinet Tambour Shutter models are very basic and simple.

  • Q. What is the headroom requirement for a Cabinet Tambour Shutters?

    A. None. Actually the tambour requires a 1 to 5 inch radius, depending on model. Mini Roll-Ups can fit into a space as small as 6 inches.

  • Q. Do Cabinet Tambour Shutter models come with track or guides?

    A. No. The cabinetmaker will build in a guide using the cabinet material within the cabinet itself.

  • Q. Do all Cabinet Tambour Shutter models require side room?

    A. Yes. The cabinet groove for the CTS-M is 15/32 x 7/8 inch. All other models require a groove of 1/2 x 3/4 inch.

  • Q. Should Cabinet Tambour Shutters have a cabinet access panel?

    A. It would make installation and removal much easier. They are usually located on the back of the cabinet.

  • Q What kind of locking devices secure the Cabinet Tambour Shutter?

    A. Cabinet Tambour Shutters have two types of bottom bar locking each working with a keyed cylinder. One is a hook bolt lock activated to engage into a separate extrusion called a lock channel or into a recessed lock plate. The other type has slide throw knobs that push a rod into the sides of the cabinet that secure the shutter.

  • Q. Can the locks be master keyed on a Cabinet Tambour Shutter?

    A. Yes. We can use small format interchangeable cores (SFIC) that are easily substituted in place of the factory mortise cylinder for an additional charge.

Mini Roll-Up

  • Q. There are terms such as mini shutters, counter shutters, coiling shutters, mini roll up shutters, hurricane shutters are all these correct to describe your product?

    A. Yes with one exception. Mini Roll-Up shutters are not hurricane shutters and should not be used in areas where that code is required.

  • Q. What is the maximum width for a Mini Roll-Up shutter?

    A. Depending on the model, it could go as wide as 10 feet 6 inches.

  • Q. What is the maximum height for a Mini Roll-Up shutter?

    A. Again, depending upon the model shutters can go as high as 14 feet.

  • Q. Are the large Mini Roll-Up shutter motor operated?

    A. Almost always. Motor operation provides easy and convenient control no matter what the size is. There are cost factors up front but these motors have the added benefit of being very quiet because they are in the axle in the coil box not hanging on the outside. The motor being in the coil box allows installations in tight spaces.

  • Q. Do you use motors on smaller Mini Roll-Up shutter openings?

    A. Yes, especially Mini Roll-Up models because the motor is inside the axle in the coil box making for a very clean look and simple installation.

  • Q. Is there any other method of operating a Mini Roll-Up shutter besides manual push up or electric motor?

    A. Yes, another choice is an awning crank with a removable rod. The hook protrudes a few inches from the coil box. The cranks are slow and somewhat tedious to use on full height shutter. Shutters also have a pull strap method of operation. This is used for smaller openings and is the least expensive. The straps are also the least reliable over time.

  • Q. What is the headroom requirement for a Mini Roll-Up shutter?

    A. Headroom can vary from 6 to 12 inches depending on the height of the shutter. Mini Roll-Ups can fit into a space standard rolling can not.

  • Q. Do Mini Roll-Up shutters require side room?

    A. Yes. If the grille is mounted face of wall to give maximum clear opening you will need room for the width of the side rails or guides. If the track is mounted between jambs, the clear opening is going to be smaller because the side rails/guides are within the opening.

  • Q. Can a Mini Roll-Up shutter be master keyed to the building keying system?

    A. At this time, Yes. We have a bottom bar/base slat that can handle a Best type cylinder.

Roll and Fold

  • Q. What areas are best suited for the Roll and Fold?

    A. First of all this product is for pedestrian control and light security. It is extremely useful in areas that have extremely high ceilings or floors that should not be drilled into. One example; airport kiosks, another is to close off access to a mall after hours while the movie theater is still open. A very popular one is a store within a store that has shorter hours then the host store.

  • Q. Is there a maximum width for Roll and Folds?

    A. Not really. The maximum panels we recommend without a bipart connection is 7 panels. Location circumstances can raise or lower that number.

  • Q. Is there a maximum height for Roll and Folds?

    A. The standard height from floor to top of panels is 6 foot 6 inches. This is not a high security partition; it is designed to keep honest people honest.

  • Q. How does someone properly operate a Roll and Fold?

    A. Not alone. Moving the product to and from the storage area requires two people. The non-marring rollers allow the Roll and Fold to travel smoothly. The anti-sway latches assist moving the partition safely by keeping the panels spread apart to avoid tipping.

  • Q. Is there any kind of track for the Roll and Fold partition?

    A. No. The Roll and Fold is extremely flexible and does not use a track system.

  • Q. How wide are the Roll and Fold panels?

    A. Curtains panels are standard widths of 36 and 42 inches. Dynamic will customize sizes to accommodate special existing conditions.

  • Q. How do the locking posts work on a Roll and Fold and where are they?

    A. Locking posts work the same as standard side folding post. The hook bolt lead locking post is the most common to secure the partition to a wall or shelving. This post could be used on both ends. The other type of lead post is a bipart. This combination post is commonly used on larger openings to lock two partitions together. A fixed end post is just that, permanently attached to a structure. This post can be used if the partition is not stacking to a remote location.

  • Q. Does the Roll and Fold need floor sockets?

    A. No. Floor sockets can be of use only if the partition needs to follow a specific lease line. The Lock Rod and floor socket can help keep the partition in position. Not highly recommended because the Lock Rod can be pull out of the floor socket.

  • Q. How big is the Roll and Fold curtain when stacked?

    A. Roll and Fold panels are 36 or 42 inches wide. Panels that have locking post will be an additional 3-1/2 inches wider. The depth is 2 inches per panel. Remember the partition is actually 115% of the opening because the panels open alternately at 135 degrees for stability, not a flat 180 degrees.

  • Q. What size should the storage area be for a Roll and Fold?

    A. The stacked partitions actual depth will vary to the number of panels that comprise the curtain used to secure the opening. Using 2 inches per panel by the width of the widest panel and add a couple of inches for clearance should get you close. Consult factory for an accurate estimate.

Rolling

  • Q. There are terms such as rolling grilles, coiling grilles, overhead grilles, roll-up grilles, which is correct?

    A. All of the above!

  • Q. What is the maximum width for a rolling grille or closure?

    A. Depending on the model, it could go as wide as 30 feet. The difficulty is two fold. One is from the limitations on freight the other is the problems of installation of the grille. Many LTL carriers today use PUP's that can only take freight up to 26 foot 6 inches maximum length. A special truck to take longer lengths can costs thousands of dollars extra. Since we are talking about thousands of dollars extra costs, installation on this size rolling grille is extremely difficult and takes a very experienced crew. This size opening is no problem for side folding grilles and should be at least considered.

  • Q. What is the maximum height for a rolling grille or closure?

    A. Standard height is between 8 feet to 14 feet, but we have built grilles as high as 20 feet. Models and total size will dictate if a grille can be built oversized.

  • Q. Are the large rolling curtains motor operated?

    A. Always. Motor operation provides easy and convenient control no matter what the size is. There are cost factors up front and the motors require space either to the side, top or front of the coil.

  • Q. Do you use motors on smaller rolling door openings?

    A. Yes, if the situation calls for it. One example, locking for rolling grilles is located in the bottom bar. To meet ADA recommendations a motorized grille with a lock brake operated by a keys witch takes away the need for locking on the floor.

  • Q. Is there any other method of operating a rolling grille besides manual push up or electric motor?

    A. Yes, another choice is an awning crank with a removable rod. The hook protrudes a few inches from the ceiling. The cranks are slow and somewhat tedious to use on full size rolling grilles. Cranks are a better option for Mini Roll-Up shutters.

  • Q. What is the headroom requirement for a rolling door?

    A. Headroom can vary from 15 to 24 inches depending on the height of the grille. Mini Roll-Ups can fit into a space as small as 6 inches.

  • Q. What can I do if I find an obstruction above the ceiling?

    A. If you are lucky and the obstruction is running parallel, you can try using "High lift" like sectional doors do, this will add to your curtain size and therefore your cost. If the obstruction is perpendicular you will need to move it or think side folding!

  • Q. Do rolling grilles or closures require side room?

    A. Yes. If the grille is mounted on 3" tubes it will require 11" total, 5 1/2" each side for the tubes and guides. Remember motor location can change your clearances as well.

  • Q. How small can I make the slot in the ceiling for the curtain to drop down from? Seems 2" to 3" should do?

    A. You will always need a minimum slot of 6 inches. On curtains over 24 feet we require 7 inches.

  • Q. Should rolling grilles and closures have a ceiling access panel?

    A. At least one, but two is better and a complete removable soffit is best. One true drawback to rolling products is not with the product, but how all the mechanisms are literally sealed away above the ceiling by the GC. This can make for difficult and expensive service calls so access panels are a smart way to go.

Side Folding

  • Q. Why are they called EZ Closures and EZ Grilles?

    A. This is the most amazing thing about the EZ models; the pocket is only 6-inches wide and fits flush with a 6-inch steel stud. That allows you to build the pocket into a wall. You just drywall over the frame, we even provide 3/4 inch drywall screws so they will not protrude through the 1/2 inch steel frame.

  • Q. Is there a maximum width for Side Folding Closures and Grilles?

    A. There is a limit of about 32 feet for EZ Closure into one pocket. Dimensions will vary based on how many posts are needed for that specific layout. Dynamic Closures has made curtains hundreds of feet (almost a hundred meters) wide with our standard side folding models.

  • Q. Is there a maximum height for Side Folding Closures and Grilles?

    A. The EZ models can be 12 feet 0 inches in height. Larger heights are available but please consult factory before you design the space. Dynamic has made a side folding grille as high as 28 feet. Most competitors do not make grilles or closures over 10 feet or 12 feet high.

  • Q. Are the side folding curtains motor operated?

    A. No, there's no need. Proper manual operation moves the curtain through some of the most creative layouts easily, saving the costs of motors and electrical hook up.

  • Q. How does someone properly operate a side folding grille or closure?

    A. It's not hard. Remember to always reach as high as possible and always try to pull the curtain. Dynamic supplies attached pull straps on all curtains 9 feet (2750mm) and over. When storing a curtain into a pocket area you will find standing at the pocket and "feeding" in the grille or closure takes literally seconds.

  • Q. Is there a bottom track?

    A. No! In fact the set clearance from the bottom of the curtain to the finished floor is 1-1/4 inches (32mm); to a counter top 3/4 in.(19mm). Sometimes floors are quite uneven and adding the optional adjustable height hardware is money well spent. The standard clearances may not be enough, or too much. It is because of these unexpected field problems that Dynamic's optional adjustable height hardware can resolve a problem and avoid a crisis.

  • Q. What is the headroom requirement?

    A. Very little. The 1-5/8 inch (41mm) height of the track is often partially or completely 'buried' by sheetrock or surface mounted on the exposed header.

  • Q. How heavy is the a side folding curtain?

    A. Curtains are various weights depending on which model you choose. It is important that the entire header-support handle the stacked weight. A comprehensive reference chart can be found on each products landing page.

  • Q. How many locking posts are there in a side folding curtain?

    A. A good rule of thumb is not to exceed a distance of 10 feet from one another for full height curtains, 6 feet for counter height. Posts should be placed on or near center of curves. This can vary slightly with different models.

  • Q. Why do we need floor or counter sockets?

    A. The floor or counter sockets accept the Lock Rods from the various locking posts and keeps the curtain in position. Remember there is no floor track.

  • Q. What is the size of the drill bit needed for floor or counter sockets?

    A. A drill bit size of 3/4 inch (19mm) for floor sockets and 5/8 (16mm) for counter sockets.

  • Q. What is the best way to drill floors like marble?

    A. Carefully! You'll need a diamond tip core drill. We suggest you consult with a professional.

  • Q. How big is the curtain when stacked?

    A. Not as big as you would think, Dynamic has the smallest stacking sizes in the industry. Amazingly, Dynamic's EZ Closure and SlimLine stacks extremely small also. You can easily calculate the size of the stack using the reference chart on the stacking dimensions page in the Details - Features and Options section of this web site.

  • Q. Why is Dynamic's standard finish clear anodized?

    A. The simple answer is to make a quality product. Unlike mill finish, a clear anodized finish will not oxidize and will be a clean grille to handle for years to come.

  • Q. Is the Pocket included with the curtain?

    A. Dynamic's EZ Closure includes a steel frame pocket and pocket door. All other side-folding models do not include a pocket. The general contractor builds the pocket and provides the door.

  • Q. Do I buy the Pocket Door from Dynamic?

    A. Again, it is included with the EZ Closure. All other models the general contractor fabricates the door on site to fit the decor.

  • Q. When I ask for a 45° curve, I am told it's a 135° curve. I don't understand.

    A. You are on the right track, just on the wrong side. A straight line is 180°. Simple math adds 45° plus 135° equaling 180°. The curved track is actually 135°. You can learn more about curves on the Track and Curves page in the Details - Features and Options section of this web site.

  • Q. I hear terms like accordion, slider, side folding, rolling, coiling and scissor grilles; what is correct?

    A. The terms accordion and scissor are often used, but side folding is the most accurate. The terms rolling, coiling and scissor apply to other products.

  • Q. What size should the pocket be?

    A. Depth of the actual stacked curtain will vary to the length of curtain used to secure the opening. Consult factory for an accurate estimate. Dynamic requires pockets to be a clear 8 inches (200mm) wide for standard curtains and a clear 13 inches (330mm) wide for Wide Body curtains. The EZ Closure only has a 6-inch width, including pocket frame, that lines up perfectly in a 6-inch steel stud wall that can be seamlessly sheetrocked over. We even supply the 3/4 inch sheetrock screws.

  • Q. How do I design a 90-degree angled pocket?

    A. You can view the most popular layouts on the right angle pocket specification page in the Details - Features and Options section of this web site. you'll also find a blocking headers for curves, that might be of help to you.
