Kwikset 300CSLSQT-15 Casey Lever Privacy Door Lock

Product Description

The KWIKSET 300CSLSQT-15 is a Casey lever-style privacy door lock featuring a square rose trim plate and a satin nickel finish. It ships with a 6AL latch and RCS strike, giving installers a complete hardware set ready for a single-point install. The lever operates a privacy function, meaning the inside button or turn piece locks the lever from the outside without a keyed cylinder — the standard configuration for bathrooms and bedrooms. Finish is satin nickel, a corrosion-resistant option common in residential interior applications. The set weighs 1.5 pounds and is sold as a single unit.

This lock is intended for interior residential doors where privacy — not keyed security — is required. Typical install locations include bathrooms, bedrooms, and home office doors. The square rose design suits transitional and contemporary trim styles. The Casey lever profile is a straight, angular lever suited to modern door hardware schemes. The 6AL latch and RCS strike included in the package eliminate the need to source compatible hardware separately, streamlining rough-in on new construction and remodel work alike.

Designed as an OEM-style replacement or new-installation privacy lock for standard residential interior doors with a 2-3/8 inch or 2-3/4 inch backset latch bore. Confirm door prep dimensions before ordering; no specific compatible model data was provided in the product input.

Installation Notes

Installation is typically performed by a finish carpenter, locksmith, or knowledgeable DIYer using a Phillips screwdriver and a door-prep kit if boring is required. Verify the existing door bore diameter and backset measurement before installation. The privacy function emergency release should be confirmed operational after installation — most privacy levers include a small slot or pinhole on the exterior rose for emergency unlock using a straightened paper clip or similar tool. No electrical or low-voltage work is involved.
