Frequently Asked Questions

Dynamic has been making the world's finest closures and grilles for quite some time, and over the course of the years we have come to anticipate what our customers are looking for - before they even think to ask! In this section of the web site, we have compiled a list of the most Frequently Asked Questions. If by chance we have missed something, or if you would like a certain point more fully explained, simply use our handy Contact Us form to drop us note.
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. Is there a maximum width for side folding closures and grilles?
A. Dynamic Closures has made curtains hundreds of feet (almost a hundred meters) wide. There is a limit of about 32 feet (9754mm) for EZ Closure into one pocket.
Q. What is the maximum height?
A. Dynamic has made a grille as high as 28 feet (8500mm). Dynamic Closures' unique designs are engineered with fewer friction points for smooth operation. Most competitors do not make grilles or closures over 10 feet (3000mm) or 12 feet (3600mm) high.
Q. Are the large 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 adjustable height hardware can resolves a problem and avoid a crisis. Note: Window Guard models can have bottom track because they are in windows not across entrances.
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 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 the load requirements page in the details section of this web site.
Q. How many locking posts are there in a curtain?
A. A good rule of thumb is not to exceed a distance of 10 feet (3000mm) from one another for full height curtains, 6 ft. (1800mm) 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. A drill bit size of 3/4 inch (19mm) A. The floor or counter sockets accept the drop bolts from the various locking posts and keeps the curtain in position. Remember there is no floor track.
should do it.
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) should do it.
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 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. 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 three of the most popular layouts on the right angle pocket specification page in the details section of this web site. Also in the details section is blocking headers for curves, that might be of help to you.
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 curve details page in the details section of this web site.
Q. How do I get more information?
A. It is easy to contact Dynamic Closures. You can either send us an e-mail or use the contact Info feature of this web site, call our friendly Customer Service Reps @ 1-800-663-4599 or fax 1-800-205-6665.
