Mantrap can be a misleading term because the more common use for an interlocking security door system is to deny access of unauthorized personnel, not necessarily to trap individuals. Commercial banks commonly refer to their protected entrances as Security Vestibules or Access Control Portals that prevent guns from entering a building.


No matter what you call them, whether they be mantrap doors, security vestibules, access control portals, or security entrances; they’re all governed by Programmable Logic Controllers or PLCs. These robust controllers are programmed to operate interlocking doors with a variety of codes that govern the operation of the system. Either a latch & strike or magnetic lock can be used to secure the door.

Isotec’s mantrap doors can either be a stand-alone structure or use a facility’s existing doors. Electrifying existing doors with magnetic locks and door position switches can be an alternative to a stand-alone solution.

Isotec’s mantrap door systems are stand-alone structures. Our typical configurations can accommodate bi-directional foot traffic or uni-directional traffic, with dedicated lanes for entry and exit. Because we build to standardized specifications our mantraps are guaranteed and warrantied to perform as defined by the client’s scenario of operation.

Isotec uses 1200lb pull force magnetic locks to secure our mantrap doors. The “mag locks” are cycle tested and proven for durable performance for 3,000,000 cycles. In addition we utilize “bonding sensors” to insure our mag locks are bonded with the door’s armature plate.

Airports use “mantrap doors” in remote locations to limit and control access to secured areas of an airport. In this application the mantraps prevent “piggy backing” or “tail-gating” and insure only authorized personnel pass through a security entrance one at a time.

In 2012, the Department of Homeland Security (DHS) awarded Isotec the Certificate of Designation for our mantrap door systems. The award specifies that our mantraps are “Qualified Anti-terrorism Technologies” as define by the 2002 SAFETY Act. www.safetyact.gov the award specifies that the operator of the system has may trap and detain people if need be. The award also specifies that our mantraps use metal detectors and ballistic rated glass and structure for protection against acts of terrorism.

Mantraps for access control have proven to be effective and more economical than relying on security personnel fo
