Kwikset 663-26D.DS One Sided Turn Deadbolt Satin Chrome

Product Description

The KWIKSET 663-26D.DS is a one-sided turn deadbolt designed for doors that require locking from the interior only, with no exterior keyed access. The unit ships with a 2-3/8 inch backset latch, dual roller catch strike (RCS), and a 5303 full lip strike, giving installers the hardware needed for a complete installation in a single package. The satin chrome (26D) finish provides a corrosion-resistant, low-sheen appearance suited to both residential interior doors and light commercial applications. This deadbolt is installed by locksmiths, carpenters, and general contractors during new construction or retrofit door hardware work.

The 663-26D.DS is typically used on interior doors where one-sided security is required — storage rooms, mechanical rooms, interior utility closets, and similar applications where thumb-turn operation is needed from one side only with no exterior cylinder. The included 2-3/8 inch RCL latch accommodates standard door prep on most residential interior doors. The full lip strike and dual RCS hardware provide flexibility for different door frame configurations encountered in the field.
