Schlage Commercial K510330626 Emergency Button Satin Chrome

Product Description

The SCHLAGE COMMERCIAL K510330626 is a replacement emergency button designed for use with Schlage L9040 and L9440 series mortise locksets. Finished in satin chrome, this small-profile button provides the tactile activation point for emergency-function lock trim, allowing authorized personnel to quickly release or engage the lock in urgent situations. At 0.75 inches long, 0.75 inches wide, and 0.25 inches tall, it is a compact, drop-in style component. Installation and replacement are typically handled by a licensed locksmith or commercial door hardware technician during trim service or lock rekeying work.

This emergency button is suited for commercial and institutional applications where L9040 or L9440 mortise locks are installed — including corridors, storerooms, and entry doors in offices, healthcare facilities, schools, and government buildings. It serves as a direct OEM-style replacement when the original button is worn, damaged, or missing, restoring proper emergency-function operation without requiring full trim replacement.

Installation Notes

Installation and trim service on commercial mortise locksets should be performed by a qualified locksmith or commercial door hardware technician. Ensure the door is closed and the lockset is disengaged before removing trim components. Refer to the lockset manufacturer documentation for trim disassembly sequence. Do not force the button housing — improper removal can damage the mortise trim cylinder or spindle.
