Passage Lever Lockset
The Master Lock SLL0403/T6P is a straight lever lockset with a polished brass finish designed for passage doors. It operates without a key or locking mechanism, allowing free movement from both sides. The steel construction meets ANSI Grade 3 standards for residential use. It fits standard doors with a 2 1/8 inch crossbore.
Upgrade From Knob Hardware
This lever replaces round knobs to provide easier grip and operation for users with limited hand strength. The jump is worth it when accessibility or a modern lever aesthetic is the priority over keyed security. Grade 3 certification confirms it meets basic residential durability requirements. No electronic or smart functions are included.
Fits Standard Residential Doors
Installation requires a door thickness between 1 3/8 and 1 3/4 inches and an adjustable backset of 2 3/8 to 2 3/4 inches. The included strike measures 2 1/4 by 1 3/4 inches for standard frame preparation. It frees up the need for separate latch and handle components by combining them in one set. No batteries or wiring are required.
