MSB550 Mechanical Switch Bar

Building codes essentially state that egress through access controlled doors must not require prior knowledge of operational requirements. Request-to-exit push bars provide uninhibited egress through access controlled openings equipped with magnetic locks, while eliminating the need for prior knowledge of egress operation and enabling egress with a single natural motion.
