Our Side Folding Security Doors

Endless Creative Possibilities In Side Folding Security Doors

If you have room on the side of your door for the curtain pocket, a side folding door is a great option for you (if you don’t, consider an overhead rolling door. We have a variety of patterns, styles, materials, finishes and colors available in all of our commercial side folding door series. Curved tracks are no problem – they can all follow almost any degree of track curvature. We can also create custom solutions faster than other companies because we manufacture them in-house.

Side Folding Quick Links

Elite Series

If you have enough room for a wider pocket but don’t have a lot of depth available, you’ll want the New Elite’s 30% – 40% tighter stack for your project.

The New Elite also offers fewer vertical lines, and more visibility into the secured area. It’s lighter and easier to open and close, but tougher than ever.

It’s the perfect solution for retrofit situations where pocket depth is an issue – or if you can’t increase the pocket but want to extend the door.

Track and Custom Curves Specifications

Patented Continuous Hinged Construction

Our patent pending revolutionary hinge design prevents hideous soot that is commonly found with piano hinges after a few months. How do we do it? Instead of the 2-part piano hinge, our hinge is a 1-piece continuous hinge that mates with the panels that form the curtain. This hinge stays cleaner during the lifetime of the door.

Color and Material Options

Depending on the model you choose, you can get materials like aluminum rod and link construction, polycarbonate panels, perforated steel, solid aluminum or tempered glass. We also stock finishes including clear anodized, black anodized and offer optional finishes such as bronze, light bronze, champagne and unlimited powder coat finishes colors.

Optional Maglock

Make keys a thing of the past and easily unlock your door using card readers and keypads. Wall channel posts and Lead posts are now available with Maglock, the electromagnetic lock capable of withstanding 850 lbs of force. Connects to a 12/24 VDC power supply from your existing alarm system. Unlock your door using a keypad or card reader.

Easy-Change Locking Cylinders

Easily change the 1” mortise cylinder locks provided to work with your internal key system. Ongoing lock updates are just as easy and are a great way to ensure old keys no longer work. Optionally available: SFIC housing and cores.

Locking System Options

Floor And Counter Sockets

Dust proof floor sockets prevent dirt accumulation with a spring-loaded cap that closes when the lock is not inserted.

Food safe sockets for securing grilles on counters meet health code requirements. Stainless steel construction resists bacterial growth and open bottom allows any food particles to drop out the bottom to a waste bin.

Frequently Asked Questions

Dynamic Closures has made curtains hundreds of feet (almost a hundred meters) wide with our side-folding models. The only exception is the EZ series, 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.

The EZ models can be 12 feet in height. 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. 

Dynamic Closures also has height adjustable side-folding doors.

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.

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.

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.

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.

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 this calculator.

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.

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.

Our Elite models come standard with adjustable height hardware, making it easy to move the curtain up 1”, or down 1”, in ½” increments.

We can supply a variety of standard curves (90°, 120°, 135°, and 150°) to accommodate a variety of site conditions. Dynamic can also bend special curves in-house to ensure your door’s function at maximum efficiency.
