Dynamic Closures has a product for every security need. Feature-rich options included as standard, with custom options available to suit each project's unique demands.

Completely reversible for left or right-hand grip with flush-mounted hardware for a sleek look. The strongest locking posts ever, and the easiest to service.

Emergency Egress Doors

"Door within a door" fire exits available in different widths to accommodate wheelchair users and comply with ADA and local fire safety codes.

Pocket Door System

Pre-assembled and ships in the pocket for the easiest installation of any side folding door. Up to 8" wide pockets. Left and right hand openings available.

Custom Curves

Any curve configuration bent and heat treated in-house for fastest turnaround. Standard 90°, 120°, 135°, 150° plus custom angles available.

Patented Continuous Hinge

Revolutionary 1-piece continuous hinge eliminates soot buildup common with piano hinges, staying cleaner throughout the lifetime of the door.

Color & Material Options

Aluminum rod & link, polycarbonate, perforated steel, solid aluminum, or tempered glass. Finishes including anodized, bronze, champagne, and unlimited powder coat colors.

Optional Maglock

Electromagnetic lock withstanding 850 lbs of force. Connects to 12/24 VDC from your alarm system. Unlock via keypad or card reader — make keys a thing of the past.

Easy-Change Cylinders

1" mortise cylinder locks easily changed to work with your internal key system. Ongoing lock updates are just as easy to ensure old keys no longer work.

Floor & Counter Sockets

Dust-proof floor sockets with spring-loaded caps. Food-safe stainless steel counter sockets meet health code requirements for food service environments.
