Emtek CY4-PSCHCTOS5-US3 Double Cylinder Deadbolt Outside Cylinder

Product Description

The EMTEK CY4-PSCHCTOS5-US3 is a double outside cylinder component designed for use with Emtek deadbolt assemblies in US3, US4, US7, and US3NL finish families. This cylinder replaces or supplements the exterior-facing lock cylinder in a double-cylinder deadbolt configuration, requiring a key for operation on both sides of the door. At 4.13 inches in length, 2.25 inches in width, and 1 inch in height, it is sized for standard residential and light commercial door preparations. Locksmiths and door hardware installers handle this type of component during new installation or cylinder replacement service calls.

This outside cylinder is intended for double-cylinder deadbolt applications where keyed entry is required from the exterior. It is finish-matched to US3, US4, US7, and US3NL Emtek finish lines, making it a direct fit for coordinating with existing Emtek hardware on the same door. Typical use cases include residential entry doors, interior access-controlled doors, and light commercial applications where consistent hardware finish and double-sided key operation are specified.
