The MUTEX SECURITY DLS3-B Commercial Privacy Door Lock eliminates restroom guesswork with a large indicator window that displays a bold green “VACANT” or red “IN-USE” signal—visible from over 50 feet away. Built to ANSI Grade 2 standards, this lock features stainless steel construction with a nickel-plated finish that resists moisture, grease, and corrosion. Ideal for office buildings, restaurants, medical facilities, gyms, and other high-traffic environments. Installation is straightforward. The DLS3-B fits standard doors 1 3/8" to 2" thick with an adjustable latch for 2 3/8" or 2 3/4" backset. All mounting accessories are included. For safety, an exterior notch allows emergency release using a flathead screwdriver or coin—preventing accidental lockouts without damaging the door. Inside, a simple thumb turn engages the privacy lock while the occupancy indicator automatically updates. The matte black finish delivers a clean, professional look suitable for both commercial and residential applications.
