Mantrap Door


The phrase “mantrap” can be a misleading term as it can often be taken falsely as a door that traps a person. However, mantraps are actually interlocking access control tools that’s purpose is to deny access to unauthorized personnel, usually from an exit and an entry door. Neither of which can be unlocked at the same time.

Mantrap Security

Several market verticals are known for using these security technologies to help increase the safety and security of their buildings. Two examples of this include airports and municipal buildings. Airports use mantrap access control in remote locations to limit and control access to secured areas of an airport. In this application, the mantraps prevent “piggybacking” or “tailgating” and ensure only authorized personnel pass through a security entrance one at a time.

However, no matter what you call them, whether they be mantrap security doors, security vestibules, access control systems, or security entrances; these systems are all governed by Programmable Logic Controllers or PLCs. These intricate and 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 Access Control

Isotec’s mantraps can either be stand-alone structures or use a facility’s currently existing doors. Electrifying existing doors with magnetic locks and door position switches can be an alternative to a stand-alone solution. In truth, mantraps for access control have proven to be effective and more economical than relying on security personnel, specifically for government and municipal buildings.

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 mantrap security entrances are guaranteed and warranted to perform as defined by the client’s scenario of operation.

What sets us apart:

  • We use 1200lb pull force magnetic locks that have been cycle-tested and proven for durable performance for 3,000,000 cycles.
  • We utilize “bonding sensors” to ensure our mag locks are bonded with the door’s armature plate.
  • In 2012, the Department of Homeland Security (DHS) awarded Isotec the Certificate of Designation for our mantraps and our other access control systems.
  • We use metal detectors and ballistic rated glass and structure for protection against possible threats.
