Yale 4605LN Storeroom Lever Lockset

The Yale 4605LN is a commercial-grade cylindrical lockset built for storeroom function where the outside lever remains locked at all times. It suits offices, storage rooms and secure areas that require key-only entry from the corridor side. The lock meets ANSI/BHMA A156.2 Grade 2 standards and carries UL and cUL three-hour fire ratings. ADA-compliant lever design ensures accessible operation for all users.

Mechanical operation with bright brass finish

This lockset operates purely mechanically with no electronic components, so it draws no power and produces no noise during use. The heavy-gauge steel chassis and six-pin cylinder resist physical attack while the bright brass 605 finish provides corrosion resistance. Two keys are supplied keyed differently for immediate installation. California Proposition 65 notices apply to materials used in the product.

Fits standard commercial door prep

The lockset installs in doors 1-3/8 to 1-3/4 inches thick with a 2-3/4 inch backset and accepts a 2-1/4 by 4-7/8 inch strike plate. The 3-3/8 inch rose covers standard cylindrical cutouts without additional machining. Right-angle Augusta lever style clears adjacent hardware and trim. This storeroom function cannot be unlocked from the outside without a key, so it is not suited for passage or privacy applications.

Questions about this item

How do I install the 4605LN lever on a door that is 1-3/4 in. thick and what step is often missed?

Fit the latch into the 2-3/4 in. backset bore, mount the chassis, then secure the rose with the two through-bolts — many forget to tighten both bolts evenly, causing the lever to bind.

What maintenance or replacement will the 4605LN need after extended use?

Periodically lubricate the 6-pin cylinder with dry graphite; if the latch bolt sticks or the lever feels loose, replace the spring cage or the entire cylindrical chassis.

What limit appears first on the 4605LN during continuous heavy traffic?

The Grade 2 spring cage reaches its cycle limit before the 3-hour fire-rated latch or the UL-listed strike, so plan replacement when lever return slows.
