ABSTRACT:
An adaptable latch having a bolt case. A bolt case extension is connected to the rear of the bolt case. The bolt case extension can be locked in position with the bolt case to place the latch in a short-length position or a long-length position. A bolt head is disposed in the bolt case. A bolt tail is connected to the rear of the bolt case. The bolt tail can be locked in position with the bolt head to place the latch in the short-length position or the long-length position. A spring-loaded lug allows for simultaneous unlocking of the bolt tail from the bolt head and the case extension from the bolt case. The bolt tail and case extension, when unlocked from a previous locked position, can be placed in another locked position to lock the latch in either the desired long-length position or the short-length position. The bolt tail is locked into position with the bolt head by way of a bolt tail appendage extending into a bolt head hollow. The bolt tail appendage locks with a bolt head catch in the bolt head hollow.
