Right-Hand Mortise Lock for Commercial Doors

The Simplex 8148M-RH-26D is a heavy-duty mechanical pushbutton mortise lever lock finished in satin chrome. It provides keyless exterior access via a single programmable code while allowing free egress from the interior. The vandal-resistant keypad features solid metal pushbuttons and operates without batteries. It carries a three-hour UL/ULC fire rating for "A" labeled doors.

Fits Standard Mortise Prep

This unit fits wood or metal doors 44 to 57 mm thick with a standard 86 mortise preparation and a 70 mm backset. It includes a 19 mm two-piece anti-friction latch and a 4-7/8" x 1-1/4" x 1/4" deadbolt strike plate. The lock accepts LFIC Medeco, Assa Abloy, or Yale 5 or 6 pin cores, which are sold separately. A unified trim plate and fixed ADA compliant lever complete the hardware.

Upgrades From Keyed-Only Mortise Hardware

This lock replaces traditional keyed mortise sets where code-based access removes the need for physical key management. The jump is worth it when traffic volume makes key distribution impractical or when battery maintenance on electronic locks is undesirable. It is not suited for applications requiring multi-code scheduling, audit trails, or remote access control. Buyers needing a left-hand configuration or a different backset must select another model.
