Mechanical Pushbutton Mortise Lever Lock

The Simplex 8146S-LH-26D is a heavy-duty mechanical pushbutton mortise lever lock with a satin chrome finish. It provides exterior access by combination while allowing free egress. The lock is designed for LFIC Schlage cores, which are sold separately. It features a single access code programmed via the keypad without removing the lock from the door.

Door Preparation and Handing Checks

Verify the door thickness is between 44 and 57 millimetres and that the mortise preparation matches the standard 86 cutout. Confirm the door is left-hand orientation to match the lever handing. Ensure the backset measures 70 millimetres. The lock fits wood or metal doors with a two-piece anti-friction latch length of 19 millimetres.

Upgrade From Keyed-Only Mortise Hardware

This lock replaces a standard keyed mortise lockset where keyless entry and code changes without battery maintenance are required. The jump is worth it when you need a 3-hour UL/ULC fire rating on A-labeled doors and a vandal-resistant keypad with solid metal pushbuttons. It is not for doors thinner than 44 millimetres or thicker than 57 millimetres, nor for right-hand door applications.
