Rocky Mountain Hardware 9156B-K x K234-US10SPEC LH Mortise Lockset Latch Set

Rocky Mountain Hardware's 9156B-K x K234-US10SPEC LH Mortise Lockset Latch Set is a left-handed mortise-style door hardware assembly from RMH designed to install in doors prepped for a mortise lock, delivering an integrated latch-set solution. The model designation indicates the trim components used (9156B-K with K234-US10SPEC) and the US10SPEC finish code applied to the lock and trim, standard for Rocky Mountain Hardware's satin-bronze family. As a mortise lockset, it embeds a lock mechanism and latch into the door edge, forming a single unit that coordinates with compatible Rocky Mountain Hardware trim to maintain a consistent architectural appearance. Specifying a left-hand handing, this set is intended for doors prepared for RMH mortise configurations and is suitable wherever a durable, integrated mortise lock is required.
