Aged Bronze Privacy Knob Lockset

This light-duty knob lockset from Master Lock provides a privacy function for interior doors such as bedrooms or bathrooms. The aged bronze finish coordinates with traditional hardware styles. It is supplied with two KW1 keys and meets ANSI Grade 3 residential standards.

Adjustable Backset and Strike

The latch assembly fits both 2-3/8 inch and 2-3/4 inch backsets without extra parts. A solid brass cylinder resists wear and a 1-3/4 by 2-1/4 inch strike plate is included. UL listing for three-hour fire doors adds code compliance for rated openings.

Simple Installation With Common Tools

A 2-1/8 inch crossbore and standard door thickness range of 1-3/8 to 1-3/4 inches allow direct replacement of most residential knobs. Misaligned strike plates or incorrect backset selection are the typical issues that prevent the latch from engaging fully.

Questions about this item

Will the solid brass cylinder need replacement after years of daily use?

The solid brass cylinder is built for Grade 3 residential durability and should not require replacement under normal interior use; lubrication with graphite powder every year or two keeps it operating smoothly.

Which component reaches its limit first when the lock is operated repeatedly throughout the day?

The spring-loaded latch bolt inside the steel chassis is the first part to show wear under very high cycle counts, though Grade 3 testing covers typical household traffic.

Does the lock generate noticeable heat or noise when the privacy turn-button is engaged for long periods?

No — the mechanical privacy function has no powered parts, so it produces no heat and only a faint click when the turn-button is thrown.
