AutomationDirect Trapped key systems

The Dold trapped key system uses a series of mechanical locks and keys to control the access of gates or doors to running equipment or machines, ensuring safe access to those machines. It provides a full trapped key safety system, in one- to five-gate sets. All keys and their corresponding receivers and modules are unique within a set. The SX series of standard gate sets are 316L stainless steel body interlock safety switches, and the ZRH series solenoid gate sets are interlocking safety switches with 24-Vac/dc solenoid power to unlock.
