Mechanical pushbutton mortise lever lock

This Simplex 8148B-LH-26D is a heavy-duty mechanical pushbutton mortise lever lock finished in satin chrome. It provides exterior access by combination with free egress from the interior. The lock fits wood or metal doors with standard mortise preparation and a 3-hour UL/ULC fire rating on "A" labeled doors.

Suits doors prepared for SFIC cores

This lock suits installers fitting doors 44 to 57 mm thick with a 70 mm backset and standard 86 mortise prep. It is not for doors outside that thickness range or for buyers who need a cylinder included, because the SFIC core is sold separately.

Left-hand lever with 19 mm latch and 25 mm deadbolt

The single specification that decides fit is the left-hand lever orientation combined with a 19 mm two-piece anti-friction latch and a 25 mm deadbolt throw. These dimensions must match the door preparation exactly.

Questions about this item

What SFIC core do I need to operate the key override on this 8148B-LH-26D?

The lock accepts a Best or equivalent 6- or 7-pin SFIC core, which is sold separately and must be installed before the key override will function.

Will this mortise lock fit the 86 cut-out already in my 44 mm to 57 mm door?

Yes, it is designed for standard 86 mortise preparation and fits wood or metal doors 44 mm to 57 mm thick.

How can I confirm the latch and deadbolt are engaging correctly after installation?

Operate the lever and key; the 19 mm anti-friction latch should retract smoothly and the 25 mm deadbolt should throw fully into the 4-7/8" strike without binding.
