Overview
About this product
Schlage's Longitude lever on the ND53 entrance function gives a locked-until-unlocked door, which suits entrances and offices where the lock should not release on its own. The button inside is pushed and turned to lock the outside lever, and it stays locked until the button is turned back.
The lock has a 3-7/16 in. Rhodes rose, a deadlatch with a 1/2 in. throw, and a single cylinder. It is ANSI/BHMA A156.2 Series 4000 Grade 1, UL/cUL listed for 3-hour fire doors, ADA compliant, and fits 1-5/8 to 2-1/8 in. doors at a 2-3/4 in. backset.
What the function does
Pushing and turning the inside button locks the outside lever. The outside lever then stays locked, and opening it from outside takes a key, until someone manually turns the button back to unlock it.
