Right-Hand Mechanical Mortise Lock

This right-hand mortise lock uses a mechanical push-button keypad for keyless entry and a lever handle for egress. It is built for heavy-duty use on wood or metal doors prepared with a standard 86 mortise cut-out. The satin chrome finish resists wear in high-traffic commercial or institutional settings.

SFIC Core Compatibility Limits

The lock accepts SFIC Best and equivalent 6- or 7-pin cores, which are sold separately, so a core must be sourced before the lock can be keyed. It fits doors between 44 mm and 57 mm thick, and the 70 mm backset is fixed, so doors with a different backset cannot use this model. The single access code is programmed at the keypad without removing the lock.

25 mm Deadbolt Throw

A 25 mm deadbolt throw provides the primary physical security barrier when the lock is engaged. The 19 mm two-piece anti-friction latch handles daily passage, while the deadbolt extends deeper into the strike for locking. Buyers who need a different throw length or a latch-only function should select another model.

Questions about this item

Should I pick the right-hand or left-hand version of the 8148?

This model is right-hand only; choose it when the hinges are on the right as you face the door from the outside.

What does the 70 mm backset mean once the lock is fitted?

The spindle centre sits 70 mm from the door edge, matching standard mortise prep for 44 mm to 57 mm thick wood or metal doors.

Does the SFIC core interface limit which cylinders I can use?

It accepts Best and equivalent 6- or 7-pin small-format interchangeable cores; the core itself is sold separately.
