摘要:
A fenestration operation hardware assembly includes at least one latch mechanism and an operation hardware assembly configured for coupling with a panel slidable within a frame. The latch mechanism includes a latch bolt and a latch biasing element coupled with the latch bolt. An operator of the operation hardware assembly is remote from the latch mechanism and is coupled with the panel. The operator includes an operator interface feature movable between initial and operating positions. In the initial position the latch bolt is in a projecting position, and in the operating position the operator interface feature moves the latch bolt into one or more withdrawn positions. The operation hardware assembly includes a retention assembly for retaining the latch bolt in a withdrawn position.
