Deltana CL504FRCNC Commercial Storeroom IC Core Grade 1, Clarendon Lever less Cylinder

No cylinder is included. The CL504FRCNC is built for an interchangeable core and ships less cylinder, so you supply the IC core in your own keyway and keying system. That is the point of the configuration: a locksmith or facility can key it into an existing master system by dropping in the core. Budget for one core per lock.

Storeroom function means the outside lever is always locked. Key retracts the latch for momentary entry, and the lever relocks as soon as the key is withdrawn. Inside lever always retracts the latch for free egress. There is no way to leave it unlocked, which is exactly what you want on a storeroom, mechanical room, electrical closet, or IT room where the door must never be left open by accident.

That is exactly the prep it is listed for: 2-3/4 inch backset and 1-3/8 inch door thickness. If your door is 1-3/4 inch (the standard commercial thickness) or your existing bore is on a 2-3/8 inch backset, this is not the right part. For a 1-3/8 to 1-3/4 inch range with a storeroom function, look at the Cal-Royal AG05 or the Hager 2580 Withnell instead.

It uses the ANSI 4-7/8 inch strike, which is the standard prep in commercial hollow metal frames. If your frame is already cut for a 4-7/8 inch ANSI strike, the strike pocket carries over. Residential frames cut for a small 2-3/4 inch face strike will need to be modified.

The Hager 2580 with Withnell lever is a Grade 2 storeroom cylindrical lock covering doors 1-3/8 inch to 2 inch thick, and the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch. Both keep the storeroom function of the Deltana CL504FRCNC Clarendon lever, which is a Grade 1 cylindrical storeroom lever in steel and zinc.

Passage and dummy levers share the same cylindrical body style but have no keyed function at all. The Falcon K101 and Corbin Russwin CL3110 are Grade 1 passage/closet levers, the Dexter C1000 passage is a Grade 1 non-keyed passage lever, and the BEST 9K 1DT is a Grade 1 non-keyed single dummy trim. None of them lock. The Deltana CL504FRCNC is keyed with a single-cylinder storeroom function, so the lever is always locked from outside and released by key.

Storeroom function on the Deltana CL504FRCNC Clarendon lever keeps the outside lever locked at all times with key entry only. For an office-style opening where the user controls the lock, the Falcon B511CP6D is a Grade 2 cylindrical lever with entry/office function, the Hager 2525 is a Grade 2 commercial cylindrical entry lever for doors 1-3/8 inch to 2 inch, and the Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body for doors 1-3/8 inch to 1-3/4 inch.

The CL504FRCNC is built for an interchangeable core, so the cylinder is ordered separately to match an existing keying system. If you want the keyway supplied, the Cal-Royal AG05 Grade 2 storeroom lever and the Cal-Royal AG00 entrance lever use a 6-pin Schlage C keyway keyed different, and the Arrow MK33-BD-CS asylum lock uses a conventional cylinder in Schlage C keyway.

No handing to specify. The Clarendon CL504FRCNC is universal handed, so one part number covers left and right hand doors and you can stock a single SKU across a building. Handle the swing at install.

It is a Grade 1 commercial cylindrical lockset with a steel and zinc body, which is the top ANSI/BHMA duty tier for cycle life and strength. That is the grade specified for schools, healthcare, and multi-family common areas. Many lever locks on the market are Grade 2 or Grade 3 and are not equivalent.

Go interchangeable core when you manage keys across many doors. The CL504FRCNC takes an IC core, so rekeying a door is pulling one core with a control key rather than pinning a cylinder or pulling the lock apart. If you only have a handful of doors and no master key system, a storeroom lever with a conventional cylinder already keyed, such as the Cal-Royal AG05 or Hager 2580, is simpler because there is no separate core to source.

The Clarendon CL504FRCNC is listed at 1-3/8 inch, so on a 1-3/4 inch leaf look at another Grade 1 cylindrical line. The Dexter C1000 Series covers 1-3/8 to 1-3/4 inch, the Falcon K Series covers 1-3/8 to 2-1/4 inch, and the Corbin Russwin CL3100 Series covers 1-3/4 to 2 inch. Specify the keyed storeroom function within whichever series you choose.

It is a tubular cylindrical lockset, not a mortise lock. That means a round cross bore through the face of the door and a latch bore in the edge, no mortise pocket to rout. Prep is on a 2-3/4 inch backset with the ANSI 4-7/8 inch strike in the frame.

The Dexter C1000 classroom is a Grade 1 clutching keyed classroom cylindrical lever for doors 1-3/8 inch to 1-3/4 inch, and the C1000 classroom security version adds classroom security function at the same door thickness range. The Cal-Royal AG03 classroom lever in the AG Series uses a 2-3/4 inch backset and a 6-pin Schlage C keyway keyed different. The Deltana CL504FRCNC is storeroom function, keyed outside only with no inside key control of the outside lever.

The Deltana CL504FRCNC is a keyed cylindrical storeroom lever taking an interchangeable core. For code entry on the same style of opening, the Lockey 2835 mechanical pushbutton keyless lever lock is ADA compliant and fits doors 1-3/16 inch to 2 inch, the Lockey 1150 heavy duty mechanical keypad lever set fits 1-1/8 inch to 2 inch, and the Delaney LP250 is a Grade 2 electronic keypad leverlock.

Storeroom function on the Deltana CL504FRCNC Clarendon lever is the common choice for supply and utility rooms that stay secured. Where the opening calls for asylum function with key control on both sides, the Dexter C1000 asylum (F87) is a Grade 1 cylindrical lock for doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a heavy duty asylum/institution/utility lock with a ball knob rather than a lever.

The Deltana CL504FRCNC is a mechanical cylindrical storeroom lever with no electrical provision. For access control, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running 12VAC/DC for doors 1-3/4 inch to 2 inch, available with the NZ lever and D rose.

The CL504FRCNC Clarendon lever is a commercial Grade 1 keyed storeroom lever in steel and zinc. Residential-duty interior levers sit in a different class: the Kwikset 200BRNL Breton passage lever is Grade 3 for doors 1-3/8 inch to 1-3/4 inch, the Kwikset 300BRNL Breton privacy lever is Grade 3 over the same range, and the Callan Asheville is a Grade 3 passage leverset.

A dummy trim has no latch and mounts as a pull only. The BEST 9K 1DT is a Grade 1 non-keyed heavy duty single dummy trim cylindrical lever, the Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever in the 5400 Series, and the BEST 7KC 1DT is a Grade 2 medium duty single dummy trim. The Deltana CL504FRCNC itself is a keyed storeroom lever with a latch, universal handing.

The Deltana CL504FRCNC Clarendon storeroom lever is offered in Brushed Chrome and Polished Brass. If a brass-toned lever is the requirement on a lighter-duty opening, the Bravura Miramar with round trim is a Grade 2 passage leverset in US4 satin brass, and the Cal-Royal AUS00 entrance/office lever is a Grade 3 lever with a solid brass forged body.
