Deltana CL504FLC Commercial Storeroom Standard Grade 1, Clarendon Lever, with Cylinder

Storeroom function means the outside lever is always locked. Entry from outside is by key only, and the inside lever always retracts the latch for free egress. There is no button or thumbturn to leave it unlocked, which is why it gets used on supply rooms, electrical closets, mechanical rooms and stock rooms where the door should never be left open. The CL504FLC is a single-cylinder lock, so the only key access is from the outside.

No. The Clarendon CL504FLC is specified for 1-3/8 inch door thickness, which is the common older interior thickness, not the 1-3/4 inch standard on most commercial openings. For a 1-3/4 inch door with the same storeroom function, look at the Hager 2580 Withnell storeroom lever, rated 1-3/8 to 2 inches, or the Cal-Royal AG05 storeroom lever at 1-3/8 to 1-3/4 inches.

It is a 2-3/4 inch backset lock with an ANSI 4-7/8 inch strike. If your frame is already prepped for a standard ANSI strike and the door bore is on 2-3/4 inch centers from the edge, it drops in. Doors bored at the 2-3/8 inch residential backset will not line up.

Yes. The cylinder is a Schlage C keyway, so it takes standard SC1/C-keyway blanks and can be worked into an existing Schlage C system. Keying is specified at order time: choose keyed different or keyed alike, and if you need it cut to an existing system you can supply the key code.

The Deltana CL504FLC is a Grade 1 storeroom cylindrical leverset with a Schlage C keyway and 2-3/4 inch backset. The closest same-function alternatives are the Hager 2580 with the Withnell lever, a Grade 2 storeroom cylindrical lock, and the Cal-Royal AG05, a Grade 2 storeroom lever lockset with a deadlocking latchbolt. All three keep the storeroom function - outside lever always locked, key retracts the latch - with the Deltana carrying the Grade 1 rating and the two others Grade 2.

The CL504FLC is a keyed storeroom lock, so the outside lever stays locked at all times. For an opening that needs free passage in both directions at the same Grade 1 level, use a passage lever instead: the Falcon K101, a Grade 1 non-handed passage cylindrical lock rated for 1-3/8 inch to 2-1/4 inch doors, the Dexter C1000 passage with clutching levers for 1-3/8 inch to 1-3/4 inch doors, or the Corbin Russwin CL3110 Grade 1 vandal resistant passage lever. None of those are keyed.

No. The CL504FLC is a storeroom function, so the outside lever is permanently locked and the key only retracts the latch. For classroom control, the Cal-Royal AG03 is a classroom lever with a 6-pin Schlage C keyway and 2-3/4 inch backset, matching the Deltana's keyway and backset, and the Dexter C1000 classroom is a Grade 1 keyed clutching lever for 1-3/8 inch to 1-3/4 inch doors. The Dexter C1000 classroom security version adds key control from both sides.

The Deltana CL504FLC uses a Schlage C type keyway. Among other cylindrical locks on the same keyway, the Cal-Royal AG03 classroom lever and Cal-Royal AG00 entrance lever both use a 6-pin Schlage C keyway keyed different, and the Arrow MK33-BD-CS asylum lock uses a conventional cylinder in Schlage C. That lets storeroom, classroom, and entrance openings run on one key system.

Handing is not a concern. The Clarendon lever is universal, so one part covers left and right hand doors, which is what you want when you are buying a batch for a building and do not want to count swings.

It is a Grade 1 commercial cylindrical (tubular) lockset with a steel and zinc body, which is the top ANSI/BHMA durability tier and the grade normally specified for high traffic commercial and institutional openings.

The Clarendon storeroom lever mounts with fixed through-bolts, so the two sides clamp through the door rather than relying on screws into the chassis alone. Nothing additional is needed for mounting on a correctly prepped door.

Storeroom is the wrong pick for either. It keeps the outside lever locked at all times with no way to hold it unlocked, so an office that needs to be left open during the day should use an entrance/office function such as the Falcon B511CP6D, and a classroom needs classroom function like the Cal-Royal AG03 or the Dexter C1000 Classroom. Use the Clarendon CL504FLC where the door must stay secured around the clock.

They are not the same. The CL504FLC storeroom function keeps the outside lever locked with no way to leave it unlocked. An entrance/office lever lets a user leave the outside lever free - the Falcon B511CP6D is a Grade 2 entry/office cylindrical lever, the Hager 2525 is a Grade 2 commercial entry lever for 1-3/8 inch to 2 inch doors, and the Cal-Royal AG00 is an entrance lever with a 6-pin Schlage C keyway on a 2-3/8 inch backset. Choose entrance only if you want that unlocked-daytime behavior.

The CL504FLC uses a Schlage C keyed cylinder. If you would rather run codes than keys, the Lockey 2835 is a mechanical pushbutton keyless lever lock that is ADA compliant and fits doors 1 3/16 inch to 2 inch, the Lockey 2835DC adds a double combination, and the Lockey 1150 is a heavy duty mechanical keypad lever set for 1-1/8 inch to 2 inch doors. The Delaney LP250 is an electronic keypad leverlock at Grade 2. Note these Lockey units are passage function, so they do not hold the outside lever permanently locked the way the storeroom Deltana does.

Several Grade 1 levers share the look but not the job. The BEST 9K 1DT single dummy trim and the Accentra 455LN Augusta single dummy are non-keyed dummy trims with no latch at all - they pull only. The Corbin Russwin CL33903 is an electrified 12VAC/DC fail safe lever that requires power and wiring. The Dexter C1000 asylum (F87) is Grade 1 but keyed both sides. The CL504FLC is a mechanical keyed storeroom lever with a single cylinder, so none of those swap in directly.

Yes - the CL504FLC is a keyed storeroom lever for commercial openings, which is not what a restroom or bedroom wants. Use a privacy function instead: the Hager 2540 with the Withnell lever, the Arrow MK02-TA Grade 2 privacy with Tudor knob and fire rating, or the Kwikset 300BRNL Breton privacy lever for 1-3/8 inch to 1-3/4 inch doors.

Three: Oil Rubbed Bronze, Brushed Chrome and Polished Brass. If you are matching existing openings, Brushed Chrome reads closest to satin chrome trim, Polished Brass to bright brass, and Oil Rubbed Bronze to dark bronze hardware.
