Emergency Door Lock

An emergency door lock is an entrance lock where the deadbolt and the knob/lever latch are linked with an interconnect device. The interconnect device makes the deadbolt and door latch open from the inside with one single action. The single action (unlock and open) function makes for a quick and easy exit from a building during an emergency. Some municipalities require an interconnected or emergency egress lock for apartments or residences. In this collection, we have emergency egress locks for residential applications, though we do carry options for commercial use  in another collection.
