Master Lock BLC0132DKA4 Entrance Knob Lockset

Product Description

The MASTER LOCK BLC0132DKA4 is a Grade 2 entrance knob lockset finished in brushed chrome, designed for standard residential and light commercial door applications. It features a 6-pin Schlage C type cylinder and a 2.75-inch backset, making it compatible with the most common door prep configurations found in pre-hung door units. The lockset accommodates door thickness up to 1-3/4 inches and is constructed from steel for durable everyday performance. Installation is straightforward for a licensed locksmith, general contractor, or experienced handyman working within standard residential door hardware replacement or new-construction finish-out work.

This entrance knob lockset is suited for residential entry doors, apartment unit doors, and light commercial interior or exterior doors where keyed entry from the outside and a turn-button or lever function from the inside is required. The keyed-alike configuration means multiple locksets in this series can be ordered to operate on the same key, simplifying key management in multi-door applications such as rental properties or small commercial suites. The brushed chrome finish coordinates with a wide range of contemporary and transitional door hardware finishes.
