The 2190-322-201-10B series Deadlock/Deadlatch combines the access control capabilities of a latch with the security of a deadbolt. The key retracts and extends the deadbolt (and deadlatch) from either side. The exterior lever retracts the latch only while the inside lever retracts the deadbolt and latch simultaneously for fast, easy, panic-proof exiting. It operates in such a way that the latch holdback feature activated or deactivated by turning key to retract latch and sliding holdback button on faceplate down to hold and up to release. It is intended for out-swinging doors.
