ABSTRACT:
The latch assembly is provided with a locking collar and a pair of knockouts so that the latch assembly can be easily converted to a latch-lock assembly by simply inserting a cylinder lock in the proper knockout, depending upon whether the assembly is used in a right-hand or left-hand installation. The conversion of the assembly may be made before or after installation of the latch-lock assembly.
