Commercial-Grade Storeroom Lever Lockset
The Yale B-AU5405LN x 626 is a heavy-duty lever lockset designed for commercial storeroom applications. It features a satin chrome 26D finish and a Best core cylinder. The 5400LN Augusta style lever provides durable operation for high-traffic interior doors requiring controlled access.
Fits Standard Commercial Door Preps
This lockset installs on doors ranging from 1 3/8 to 2 inches thick with a 2 3/4 inch backset. The front dimensions measure 2 1/4 x 1 1/8 inches to match standard mortise cutouts. It replaces existing cylindrical locksets without modifying the door or frame, freeing installers from custom fabrication work.
Mechanical Operation Withstands Continuous Use
The all-mechanical storeroom function ensures the exterior lever remains locked at all times, requiring a key for every entry. No electronic components or batteries are present to fail during extended operation. The heavy-duty construction maintains latch retraction reliability through thousands of daily cycles in demanding environments.

Questions about this item
How does the storeroom function limit access during continuous use?
The storeroom function keeps the outside lever locked at all times; entry requires a key while the inside lever always allows free egress.
Does the satin chrome 626 finish or heavy-duty construction affect heat buildup or noise during all-day operation?
The mechanical lever has no electronic parts, so it generates no heat and operates silently regardless of how long it is used.
What door preparation must already exist for the 2 3/4 inch backset and 5400LN Augusta style to install correctly?
The door needs a 2 3/4 inch backset bore, 1 3/8 to 2 inch thickness range, and a 2 1/4 x 1 1/8 inch front cutout.
