Mechanical pushbutton mortise lock for LFIC

The Simplex 8148S-RH-26D is a heavy-duty mechanical pushbutton mortise lever lock finished in satin chrome. It is designed for right-hand doors and accepts LFIC Schlage cores, which are sold separately. The lock provides exterior access by combination while allowing free egress from the interior. Its vandal-resistant numeric keypad features solid metal pushbuttons for added security.

Battery-free operation with single access code

Because the lock is entirely mechanical, it eliminates the material and labour expense of battery replacements. A single access code is programmed directly via the keypad without removing the lock from the door. The unified trim plate and cast front housing contribute to durability under sustained use on high-traffic openings.

70mm backset with 3-hour fire rating on A-labelled

The lock has a 70mm backset and fits doors 44mm to 57mm thick with standard 86 mortise preparation. It includes a 19mm two-piece anti-friction latch and a 25mm optional deadbolt. The assembly carries a 3-hour UL/ULC fire rating on A-labelled doors and features a fixed ADA-compliant lever.

Questions about this item

How much power does the 8148S-RH-26D draw when running all day?

The 8148S-RH-26D is a fully mechanical pushbutton lock with no batteries or wiring, so it draws zero power during continuous operation.

What core must I already own to operate the LFIC cylinder on this mortise lock?

You need a Schlage large-format interchangeable core; the lock ships without one and the key override will not function until that core is installed.

Will the 70 mm backset and 86 mortise prep align with the cut-out on my existing door?

Yes, the lock fits the standard 86 mortise preparation and a 70 mm backset, matching common commercial door cut-outs from 44 mm to 57 mm thick.
