When a classroom or similar room door calls for a mortise lock with the classroom function, this Corbin Russwin ML2000 series lock is built for exactly that job. It is the 55-Classroom function, ANSI F05, in a single cylinder layout, and it arrives as working trim with a wrought Lustra lever on the round A rose.
The finish is satin chrome, BHMA 626 (US26D), a matte silver look over a brass or bronze base. Handing is reversible, so you set it for the swing of the door on site rather than ordering a left or right version. The lock fits doors 1-3/4 in thick, and the supplier lists the L4 keyway.
The maker states this lock is Grade 1, cUL listed to UL 10C, fire rated for a minimum of 180 min (3 hr) on Class A labeled openings, designed for accessible operation, and BAA qualified. It is made in the United States, sold each, and backed by a 10-year limited warranty from Corbin Russwin.
