Kwikset 300CSLSQT-4 Casey Lever Privacy Door Lock Satin Brass

Product Description

The KWIKSET 300CSLSQT-4 is a Casey lever-style privacy door lock featuring a square rose trim plate, a 6AL latch, and an RCS strike plate, finished in satin brass. Designed for interior privacy applications, it provides a turn-button locking mechanism on the inside with emergency release access from the outside. The lever-and-square-rose pairing delivers a clean, contemporary profile suited to residential door installations. The complete kit ships as a single unit and includes all required hardware for a straightforward replacement or new-installation job. Licensed locksmiths, carpenters, and general contractors routinely install this type of hardware on bedroom and bathroom doors.

This privacy lock is intended for interior residential doors where occupancy privacy is needed but keyed security is not required, such as bedrooms, bathrooms, and home offices. The 6AL latch is a standard spring latch with a 2.375-inch backset, which fits the most common residential door prep. The satin brass finish coordinates with a wide range of interior hardware and trim. The included RCS strike provides a clean wall-side seat for the latch bolt.
