Kwikset 400P-5 Polo Knob Entry Lock Antique Brass

Product Description

The KWIKSET 400P-5 is a keyed entry knob lock designed for residential exterior doors. It ships as a complete entry set, including the Polo-style knob, a 6AL latch, and an RCS strike plate, so installers have every component needed for a standard door prep. The Antique Brass finish suits traditional and transitional door styles. This lock is intended for exterior passage points that require keyed entry from the outside and a turn-button or lever release from the inside. Locksmiths, finish carpenters, and general contractors install this type of hardware during new construction and remodel projects where a finished, keyed knob set is specified.

The 400P-5 fits standard residential entry door applications with a 2.375-inch or 2.75-inch backset and a standard cross-bore diameter. The included 6AL latch is compatible with common door preparations found in residential construction. The RCS strike plate coordinates with standard door-frame mortise cuts. This unit is sold individually and is appropriate for front doors, back doors, and side entry doors in single-family and multi-unit residential settings.

Installation Notes

Installation is typically performed by a locksmith, finish carpenter, or general contractor. Ensure the door is closed and any existing hardware is fully removed before beginning. Verify backset measurement before installing the 6AL latch to confirm proper alignment with the strike plate. Follow local building codes for residential entry hardware, and confirm the door edge and frame are square before final tightening to prevent binding.
