Mechanical pushbutton mortise lock

The Simplex 8146S-RH-26D is a heavy-duty mechanical pushbutton mortise lever lock finished in satin chrome. It provides exterior access by combination while allowing free egress from the interior. The numeric keypad uses solid metal pushbuttons and is vandal resistant. A single access code is programmed at the keypad without removing the lock from the door.

Fits standard mortise prep and LFIC cores

The lock fits wood or metal doors 44 to 57 mm thick with standard 86 mortise preparation. It has a 70 mm backset and a 19 mm two-piece anti-friction latch. A 4-7/8" x 1-1/4" x 1/4" deadbolt strike plate is included. The lever is fixed and ADA compliant. The lock accepts LFIC Schlage cores, which are sold separately, and carries a 3-hour UL/ULC fire rating on A-labeled doors.

Suits commercial doors needing keyless entry

This right-hand lock suits commercial installations that want code-based entry without battery maintenance. Buyers who need a left-hand configuration or a different backset should look elsewhere. It also does not suit doors outside the 44 to 57 mm thickness range or projects that require multiple access codes.

Questions about this item

How does the mechanical pushbutton design hold up when the lock is operated continuously throughout the day?

The lock uses solid metal pushbuttons and a cast front housing with a unified trim plate, eliminating battery replacements and electronic wear during sustained use.

What heat, noise or power considerations arise when the lock runs all day in a busy entrance?

As a fully mechanical lock it draws no power, generates no heat and produces only the sound of the lever and latch engaging during normal operation.

Which LFIC Schlage core must I already have to complete the key override on this mortise lock?

The lock is prepared for a Large Format Interchangeable Core from Schlage; the core itself is sold separately and must be supplied by the installer.
