Trapped Key Spring Handle Interlock with Dual Key, Chain and Lockout Dust Cover (SS-HD-11-C-LT)

The SS-HD-11-C-LT Trapped Key Interlock operates by using a spring loaded handle lock mechanism, which is locked when the first key is removed. Operating the first key allows the secondary key to be released, unlocking the handle (which is connected to a chain) and allowing access to the hazardous area. The secondary key (often referred to as the personnel key) is taken inside the hazardous area to reduce the likelihood of an inadvertent start-up.
