There are no other commercial back doors on the market as formidable that ALSO meet life safety egress codes. QMI’s patent-pending high security features, PLUS the industry leading Trident 5-point lock system with panic bar release is included-delivering unmatched performance against experienced burglars.
Trident 5-point locking system
- Trident is the Loss Prevention professional’s number one choice in anti-pry door locks.
- Fully surface-mounted hardware allows for retrofit installations into existing steel frames.
- Meets egress compliance for single action door release.
- Two latch-side, two hinge-side bolts, and one center latch surface mounted roller strike project into the frame.
- All 5 lock points release with push of panic bar.
Active Anti-Cut System
- Active anti-cut assemblies located inside door slab (Patent-Pending).
- Prevents electric and gas-powered circular and reciprocating saw attacks.
- Self-healing design stops repeated cuts at the same attack location.
- Enhances door stiffness to resist pry and impact attacks.
Hinge-side protection bracket
- Z-bracket wraps around center-web of door frame to prevent pry-bar from gaining access to door interior.
- Mounting holes slotted for horizontal adjustability during installation .
- Even with exterior hinges cut off, there still is no pry access.
Factory-direct professional installation
- Only factory-trained and certified installers will install a QMI back door for maximum protection.
- Left or right-hand outswing operation.
- Trident lock options: delayed egress alarm, battery operated alarm, exterior manual “break-away” handle, exterior card reader ”break-away” handle, Knox box, and California compliant push paddles.
2-Part interlocking astragal (latch side)
- Astragal profile on door overlaps L shaped angle on frame when door is closed to seal off access to pry-bar attempts at door seam.
Anti-Drill Plates
- Serves as a barrier to steel and carbide drill bits and hole saw attacks.
- High security drill plates are bonded and fastened to the interior door face.
Bellow are examples of ILLEGAL security devices. These not only compromise the employees, but also first responders who might need to use that exit during a fire or other call out. The QMI back door is more secure, yet still safe.
