Electromagnetic Locks: Solutions for low-risk security applications

8371/8372 Surface MiniMag®

The Surface MiniMag® locks are designed with a 1-7/8” width to keep undersized openings within code. These locks are ideal solutions for traffic control on narrow-style interior or perimeter doors. The RCI 8371 Surface MiniMag® is for single outswinging doors. The RCI 8372 Surface MiniMag® is used for double outswinging doors without mullions. These electromagnetic locks install perfectly alongside most automatic door operators or stop-mounted door hardware. They reduce installation time and eliminate the need for extra brackets.
