Master Lock BLC0432D Passage Knob Lockset Brushed Chrome

Product Description

The MASTER LOCK BLC0432D is a passage knob lockset designed for doors that do not require keyed entry or privacy locking. It functions as a turn-and-latch mechanism only, making it suitable for hallways, closets, and other interior passages. The lockset features a brushed chrome finish over a steel construction and accommodates door thicknesses up to 1.75 inches. It is rated Grade 2 under ANSI/BHMA A156.2 standards and carries a UL listing. Installation is straightforward and falls within the scope of a general contractor, carpenter, or skilled maintenance technician working on light commercial or residential interior doors.

This passage lockset is intended for interior door applications where free passage is required without a locking function. Typical installations include hallway doors, utility closets, and common-area entries in residential and light commercial settings. The 2.75-inch backset is the standard measurement used in most pre-bored door preparations. The Schlage C-type keyway cylinder and 6-pin configuration are present in the hardware but the passage function means no key operation is required for normal use.
