Kwikset 663-26.DS One Sided Turn Deadbolt Bright Chrome

Product Description

The KWIKSET 663-26.DS is a one-sided turn deadbolt designed for doors that require a keyed or thumbturn operation on one side only, with no exterior cylinder. The unit ships with a 2-3/8 inch backset RCL latch and a dual RCS configuration, along with a 5303 full lip strike plate. Finished in Bright Chrome, the 663-26.DS suits residential entry and interior door applications where a single-sided locking mechanism is required. It is installed by locksmiths, finish carpenters, and general contractors during new construction or door hardware replacement projects.

This deadbolt is well suited for residential doors where access from one side is controlled by a thumbturn or lever turn, with no cylinder needed on the opposite face. The included full lip strike and dual RCS hardware support standard door frame preparation. The Bright Chrome finish coordinates with a wide range of residential door hardware. Typical applications include interior privacy doors, utility room entries, and communicating doors where one-sided deadbolt security is the design intent.

Installation Notes

Installation is typically performed by a licensed locksmith or finish carpenter following the door manufacturer's bore specifications. Disengage all power to any adjacent electronic hardware and ensure the door is fully closed and stable before beginning installation. Follow local building codes and the door manufacturer's hardware preparation requirements. Do not force the latch or strike into undersized bore holes, as this may compromise lock function and door integrity.
