Trapped Key Spring Handle Tongue Interlock with Single Key (SS-HT)

The SS-HT Trapped Key Interlock is a safety mechanism that operates using a spring-loaded handle lock mechanism. This locking mechanism is activated when the key is removed, securing the hazardous area. Access to the hazardous area is granted by inserting and turning the appropriate key to unlock the handle. To ensure long-term reliability, IDEM has incorporated an anti-tamper cam system into the SS-HT interlock.
