Kwikset 663-15.DS One Sided Turn Deadbolt Satin Nickel

Product Description

The KWIKSET 663-15.DS is a one-sided turn deadbolt designed for doors where keyed entry is not required on one face, such as interior doors that need a security lock operable only from inside. The unit ships with a 2-3/8 inch backset latch, dual roller catch strike hardware, and a 5303 full lip strike, giving installers a complete latch-and-strike assembly in a single package. The satin nickel finish matches widely used residential hardware lines. This deadbolt is appropriate for residential door applications and is typically installed by locksmiths, finish carpenters, or general contractors during new construction or retrofit work.

The 663-15.DS fits standard residential door preparations and is suited for interior single-door applications where one-sided thumb-turn operation is the design intent. The included 2-3/8 inch backset latch accommodates the most common residential door edge bore spacing. The full lip strike and dual roller catch strike are included, reducing the need for separate hardware orders on a standard installation. This product is sold as an individual unit and is available in case quantities of 12 for multi-door projects.

Installation Notes

Installation is performed by a licensed locksmith, finish carpenter, or qualified contractor. Power tools are not required for most installations, though a drill and hole saw are needed if creating a new door bore. Verify door thickness and backset measurement before ordering to confirm the 2-3/8 inch latch is appropriate. Always follow local building codes regarding egress hardware requirements when selecting a one-sided deadbolt for any door.
