Explanation of Hinge Pin Engagement
During door installation, the connector body of the hinge pin assembly is inserted into the single or double GIB (Guide In Bracket) on the frame. The GIB provides the proper alignment for the electrical pins on the hinge pin assembly to engage the hinge pin receptacle. The lock spring located on top of the hinge pin assembly engages into the upper frame rail once the hinge pin assembly has fully engaged the receptacle locking it securely in place. Once the hinge pin assembly is fully engaged the door can only be removed by inserting a pair of needle nose pliers into the square hole in the lock spring allowing the spring to be compressed, disengaging it from the upper frame rail and allowing it to be pulled free from the receptacle.
