The Dual Force 2190 Interconnected Deadbolt/Deadlatch provides access control and security for aluminum stile doors. Latch and deadbolt capabilities are combined for fast, easy, and panic-proof exiting. The Dual Force 2190 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. Intended for out-swinging doors. Key or thumbturn retracts or extends deadbolt or deadlatch. Inside lever retracts both when configured with interconnect feature. Outside lever retracts latch only. 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. 2190 will not work without its specially designed strike - included standard in package.
