The Corbin Russwin CRMELR-48 is a motorized electric latch retraction (MELR) retrofit kit designed to upgrade existing ED4000 and ED5000 Series exit devices on 48-inch openings. This kit delivers a complete rail assembly, an integrated controller, and a touch bar end cap, giving door hardware technicians everything needed to convert a standard exit device to quiet, electrified latch retraction. The MELR technology allows for remote unlatching and momentary or continuous dogging, making it ideal for access control integrations, automatic operators, and high-traffic commercial entrances. Built to Corbin Russwin's Grade 1 standards, the CRMELR-48 offers a reliable, field-serviceable solution for retrofitting exit devices without replacing the entire unit.
