Type DC Interlock

Access interlock

KIRK® Type DC access interlocks provide a physical barrier to either partial or full body access points until risk of hazardous energy or moving equipment has been mitigated.

All Type DC interlocks have two parts; a main body with one cylinder and a catch. When the catch is separated from the main body, the key is trapped in the lock. When the door on which the interlock is mounted is properly closed, the catch can be inserted into the main body and the key can be turned and released.

The Type DC is available in both SD and HD series.

For further technical information please refer to the datasheet.
