Dormakaba lr8146b-26d-41 Mortise Lever Lock Satin Chrome

Product Description

The DORMAKABA lr8146b-26d-41 is a mechanical push button mortise lockset designed for commercial entry applications requiring key override capability. This unit features a 6/7-pin SFIC prep with Best SFIC housing (less core), allowing facilities teams to install their own core as part of an existing keying system. The lever handle is left hand reverse in orientation and finished in satin chrome. Built to ANSI Grade 1 standards, this lockset is suited for high-traffic commercial doors where durability and access control reliability are required. Licensed locksmiths, commercial door hardware installers, and facilities maintenance technicians are the primary trades that specify and install this hardware.

This lockset is intended for commercial applications including office buildings, institutional facilities, and multi-tenant properties where push button combination entry with key override is needed. The left hand reverse handing accommodates specific door swing and latch configurations common in commercial construction. The SFIC prep design allows integration with Best interchangeable core keying systems already deployed in a facility, reducing rekeying complexity during hardware upgrades or tenant changes.

Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with mortise lock prep and SFIC core systems. Verify door handing and mortise pocket dimensions before installation, as mortise locksets require precise prep work and are not interchangeable with cylindrical lock bores. Ensure the door is secure and all existing hardware is removed before fitting the mortise case. Follow applicable local building codes and ADA lever handle clearance requirements during installation.
