Accentra (Yale) AU4602LN Grade 2 Privacy Bath/Bedroom Cylindrical Lock, Augusta Lever

The Accentra AU4602LN is a Grade 2 privacy lock designed for bathrooms, bedrooms, dressing rooms, and any interior door requiring inside-controlled locking. This non-keyed cylindrical lock features the elegant Augusta lever with a 2-3/4" backset, meeting ANSI/BHMA F76 specifications for privacy function. An inside push button locks the outside lever while an emergency release on the outside allows access if needed. The inside lever remains freely operable at all times for safe egress, making this lock ideal for commercial buildings, multi-family apartments, hospitality facilities, healthcare settings, and educational institutions where user safety and privacy matter equally.

How privacy locks work and when to use them

Privacy locks let someone inside lock the door while allowing emergency access from outside. Push a button inside, and the outside lever becomes inoperable. Rotating the inside lever, closing the door, or using the outside emergency release all unlock it automatically, preventing accidental lockouts. This makes privacy locks perfect for bathrooms where occupants want security without fear of being trapped. Unlike storeroom locks that give no outside access, or passage locks that don't lock at all, privacy function balances personal security with safety. The 4600LN series delivers this balance at an economical price point suitable for high-volume commercial installations.

Emergency release and safety features for bathroom doors

The AU4602LN includes an emergency release mechanism on the outside lever, allowing caregivers, parents, or facility staff to unlock the door from outside without a key if someone is in distress. A small flat-head screwdriver or coin inserted into the release slot unlocks the door instantly. This feature is especially important in healthcare facilities, schools, assisted living environments, and family residences where safety supervision is needed. The push button on the inside lever is intuitive and foolproof, requiring no keys or complex mechanics. When the inside lever is rotated or the door closes, the button resets automatically, eliminating the risk of accidental lockouts that plague other privacy designs.

Grade 2 certification and fire-rating for commercial installations

The AU4602LN is certified to ANSI/BHMA A156.2, Series 4000, Grade 2 standards and UL-listed for 3-hour fire-rated door applications. Grade 2 certification means the lock meets minimum durability requirements for standard commercial use, capable of withstanding approximately 400,000 door cycles. This rating suits office buildings, retail facilities, medical settings, government buildings, and multi-unit residential properties. The 3-hour fire rating allows installation on fire-rated assemblies without compromising door safety ratings. Brass and bronze construction resists corrosion, and the fixed lever design prevents sag or wobble that compromises security and comfort.

Installation specifications and compatibility with standard door preps

The AU4602LN fits doors between 1-3/8" and 1-3/4" thick, accommodating nearly all commercial hollow-core and solid wood doors. The 2-3/4" backset is the industry standard on commercial locks, matching existing door preparations and simplifying replacement of worn locks without door re-drilling. The 2-1/8" bore and 3-3/8" rose diameter provide clean architectural appearance while maintaining proper mechanical tolerances. Installation requires drilling one 1" hole for the latch and two 5/16" holes for lever mounting. The non-handed design works on both left and right swing doors without modification. Standard ASA strike and wood/machine screws ship with each lock for immediate installation on any commercial door prep.
