N.C. Contact for Steel Doors & Windows

Discreetly monitor a steel door or window with the Seco-Larm Enforcer Magnetic Contact, 3/4" Recessed Steel Door (1" Gap, NC). Made of high-impact ABS plastic, the switch and magnet offer one-piece construction for strength, and gold-plated screw terminals for durability. Both pieces have ribs to fit snugly into the mounting holes. The contact works with a 1-gap in N.C. applications.
