When the main body is separated from the latch block-bolt eye, the key is retained and cannot turn in the lock. Thus, the key is always held in the lock when the two parts are separated. By closing the door on which the DY2 interlock is mounted, the latch block-bolt eye is engaged with the main body and the key can be turned and removed. The DY2 housing and latch block-bolt eye are made of zinc alloy. The dust cover and all interior parts are made of stainless steel. The exterior is painted with powder coat paint. Push On Dust Cover is included.
