It fits doors from 1 3/8" to 2" thick, is reversible, non-handed, and has cold rolled steel housing.
• UL listed latch bolt with a 2 3/4" backset. Universal across all functions.
• ANSI strike 1 1/4" x 4 7/8". All lever sets, and functions are uniform.
• five pins keyed to a six-pin solid brass SC-1 ILCO #1145 keyway.
Each lever operates independently of the others. Deadlocking latches are present on all keyed lever sets. Two nickel silver keys are provided.
