Side foldingElite Series

Tighter Stack, Shallower Pocket

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.

Cleaner Sightlines, Stronger Build

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.

Built for Retrofits

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.

Side foldingSlim Line Series

Fits Any Pocket Shape

Adapting to any pocket requirement (including curves and L-angles), the Slim Line is a great solution for any secured area.

Maximum Visibility, Minimal Stack

Most of the designs feature sleek vertical lines that allow maximum visibility for product display, even when the door is closed. The 5-inch stack allows you to use more space for your secured area than other doors.

Counter Height to 14 Feet

Fits any application: new or retrofit, counter height to full height openings up to 14 feet tall.

EZ Series: With Pocket

The EZ 4 Inch security grille includes its own steel pocket frame and anodized aluminum pocket door, eliminating the need for your contractor to build one on site.

It arrives with the door already loaded in the pocket, saving installation time.

Even better, the pocket is 6-inches wide, allowing it to fit flush with commercial wall studs for a visually seamless integration.

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.
