Kwikset 450P-26D Polo Knob Storeroom Vestibule Lock

Product Description

The KWIKSET 450P-26D is a Polo knob storeroom/vestibule lock supplied with a 6AL latch and RCS strike plate in a satin chrome finish. This lock is designed for storeroom and vestibule applications where the exterior knob is always locked and cannot be opened by turning from outside — entry requires a key at all times, while the interior knob allows free egress. The satin chrome finish provides a clean, neutral appearance suited to commercial and residential door hardware. Installation is performed by a licensed locksmith or door hardware professional and follows standard cylindrical lock prep dimensions.

The 450P-26D is well suited for interior utility rooms, storage areas, server rooms, and vestibule doors in both light commercial and residential settings where controlled single-side access is required. The included 6AL latch and RCS strike provide a complete installation package without sourcing separate hardware. The storeroom function makes this lock appropriate wherever keyed access must be maintained at all times from the exterior side.

Installation Notes

Installation should be performed by a qualified locksmith or experienced door hardware technician familiar with cylindrical lock sets.

Disengage any existing hardware and follow local building codes regarding egress requirements before completing the installation.
