Mechanical combination lever lock

The Simplex L1021C-LH-3 is a heavy-duty cylindrical lever lock that opens by pushbutton code or key override. It mounts on left-hand doors ranging from 35 to 57 mm thick and accepts a Corbin Russwin 6-pin large-format interchangeable core sold separately.

Adjustable backset and keyless entry

The lock replaces a standard cylindrical latch with a 13 by 19 mm bolt and an adjustable backset of 60 or 70 mm. The mechanical keypad removes the cost and labour of battery changes while allowing a single access code to be programmed at the door without removing the hardware.

Suits commercial fire-rated doors

This model fits wood or metal doors with a three-hour UL/ULC fire rating on A-label openings and meets ADA lever requirements. It is not for right-hand doors, doors outside the 35 to 57 mm thickness range, or installations that require multiple user codes or an included core.

What door thickness does the L1021C-LH-3 accommodate?
