Deltana CL504EVC Commercial Storeroom Standard Grade 2, Clarendon Lever with Cylinder

Yes. The CL504EVC Clarendon lever is built for doors from 1-3/8 inch up to 2 inch thick, so it covers both older 1-3/8 interior doors and standard 1-3/4 commercial doors without any spacer kit. Above 2 inches it will not through-bolt properly.

The CL504EVC comes with the 2-3/4 inch backset latch in the box. The 2-3/8 inch backset latch is a separate order, not an adjustable latch, so if your existing prep is the shallower 2-3/8 bore you need to add that latch to the order or the lock will not reach the strike. Those two backsets are the only ones used on standard cylindrical prep, so measure from the door edge to the center of the bore before you order.

No handing to specify. The Clarendon lever is universal, so one part covers left and right hand doors and you can stock a single SKU across a building instead of splitting your order by swing.

The CL504EVC uses the Schlage C keyway, so it takes standard Schlage C blanks and can be pinned into an existing SC1/C-keyway system by your locksmith. It's a single cylinder keyed lock, one cylinder outside only. If your building runs a proprietary or restricted keyway instead, this cylinder will not accept it.

It's supplied with an ANSI strike, 4-7/8 x 1-1/4 inches. If your frames are already prepped for the ANSI strike (the tall square-corner one used on commercial hollow metal frames), it drops straight in. If your doors have a small T-strike or a 2-3/4 inch round-corner residential strike, the frame cutout will need to be enlarged to take the ANSI plate.

The Deltana Clarendon CL504EVC is a keyed storeroom lever: the outside lever is permanently locked and only the key retracts the latch, with no pushbutton or thumbturn to leave it unlocked. An entrance or office function lever such as the Hager 2525 Grade 2 commercial entry lock or the Falcon B511CP6D Grade 2 entry/office lever lets an occupant set the outside lever unlocked so the door stays open during business hours. Choose storeroom for a mechanical room, stock room, or electrical closet that must never be left unsecured, and entry/office where staff need to unlock the opening for the day.

The Hager 2580 with the Withnell lever is the nearest match. Both are Grade 2 cylindrical storeroom levers, and the Hager 2580 carries a 1-3/8 inch to 2 inch door thickness range, the same range the Clarendon CL504EVC covers. Storeroom function on either one means the outside lever stays locked at all times and is retracted by key only, while the inside lever always gives free egress. For a property manager standardizing a back-of-house corridor, either lever behaves the same way at the door; the difference is the lever shape, Clarendon versus Withnell.

Not automatically - the cylinder has to be the same keyway. The Deltana Clarendon CL504EVC uses a Schlage C keyway, and Cal-Royal's AG00 entrance and AG03 classroom levers are 6-pin Schlage C, so those key into a common system. The Arrow MK33-BD-CS also carries a conventional cylinder in the Schlage C keyway. Hardware built around a different manufacturer cylinder needs an adapter to accept a Schlage cylinder; the Accentra 107S is a Schlage cylinder adapter kit for Yale hardware and exists for exactly that reason. Confirm keyway before assuming one key covers the run.

Grade 2 is the standard commercial duty level, rated for moderate traffic openings: storage rooms, back-of-house doors, tenant closets, offices. It's the right call for a door that gets used a few times a day. For a high traffic opening or an abuse-prone one, step up to a Grade 1 cylindrical lock such as the Dexter C1000 Series or the Falcon K Series. The CL504EVC body is steel and zinc.

Two direct alternatives we carry. The Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt, rated 1-3/8 to 1-3/4 inch doors. The Hager 2580 with the Withnell lever is Grade 2 storeroom for 1-3/8 to 2 inch doors, the same thickness span as the Clarendon. Pick on lever style and on whether your keyway matches, since the Deltana runs the Schlage C keyway.

It's a tubular cylindrical lockset, so it goes into standard bored cylindrical prep, a face bore through the door with a latch bore in the edge. No mortise pocket required. If your doors are already mortised for a mortise lock body, this will not fill that prep and you'd need a mortise lock instead.

The latch is UL Listed. That's the listing stated for the CL504EVC latch specifically, and it's the component that matters on a labeled opening. Check the label on your door and frame for the rating you have to meet before you commit.

Classroom function is a different keyed function from storeroom. The Cal-Royal AG03 classroom lever is Grade 2 in a 6-pin Schlage C keyway with a 2-3/4 inch backset, which matches the Schlage C keyway and 2-3/4 inch backset the Deltana Clarendon CL504EVC ships with, so it keys and preps the same way. In Grade 1, the Dexter C1000 classroom and classroom security levers cover doors 1-3/8 inch to 1-3/4 inch thick with clutching keyed trim. Classroom lets the key lock and unlock the outside lever; storeroom keeps the outside lever locked at all times.

The Clarendon CL504EVC is a Grade 2 cylindrical lever. For openings where a Grade 1 cylindrical lever is specified, the Dexter C1000 series covers Grade 1 in several keyed functions - classroom, classroom security, and entry/office - with a 1-3/8 inch to 1-3/4 inch door thickness range on those three. The Dexter C1000 asylum version is Grade 1 across 1-3/8 inch to 2 inch. Grade 1 is the heavier ANSI/BHMA cycle and strength tier; Grade 2 is the commercial tier the Clarendon is built to. Match the grade to what the drawing or facility standard calls for.

No. A passage lever such as the Hager 2510 Grade 2 or the Falcon B101 Grade 2 non-handed passage lever has no cylinder at all - both levers always retract the latch, so the opening never secures. The Deltana Clarendon CL504EVC is keyed with a single cylinder in the Schlage C keyway and is intended to keep the outside lever locked. Passage levers belong on corridor and closet doors that only need a latch; a stock room or utility door that has to stay locked needs the keyed storeroom lever.

For an inactive leaf or a false door, a dummy lever is the right part - it mounts trim only, with no latch and no cylinder. The BEST 7KC series single dummy trim is a Grade 2 non-keyed medium duty cylindrical lever, and the BEST 9K series 1DT single dummy is the Grade 1 heavy duty equivalent. The Callan Bentley is another Grade 2 dummy lever. The Deltana Clarendon CL504EVC is the keyed storeroom lever with a working latch and a Schlage C cylinder, so it is not the part for a leaf that does not latch.

Mechanical pushbutton levers replace the key with a code. The Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance, fitting doors 1 3/16 inch to 2 inch, and the Lockey 2835DC is the double combination version over the same thickness range. The Lockey 1150 heavy duty keypad lever set covers 1-1/8 inch to 2 inch. The Delaney LP250 is an electronic keypad leverlock at Grade 2, the same grade as the Deltana Clarendon CL504EVC. The trade off is that the Clarendon keys into a Schlage C system alongside the rest of a keyed facility, which a standalone keypad does not.

The Arrow MK33-BD-CS is a Grade 2 asylum function cylindrical lock in heavy duty with a conventional cylinder in the Schlage C keyway - the same keyway the Deltana Clarendon CL504EVC uses, though the Arrow carries a ball knob rather than a lever. In Grade 1 with lever trim, the Dexter C1000 asylum F87 covers doors 1-3/8 inch to 2 inch. Asylum function keys both sides; the Clarendon storeroom function keys the outside only and leaves the inside lever free for egress, which is what a code-required exit path needs.

They are built to different tiers. The Deltana Clarendon CL504EVC is a Grade 2 commercial lever in steel and zinc with a UL Listed latch, ANSI 4-7/8 inch by 1-1/4 inch strike prep, and removable through-bolts. Grade 3 levers such as the Kwikset 200BRNL Breton passage, the Master Lock RL series keyed entry, and the Callan Artino entrance leverset sit a tier below and the Kwikset covers 1-3/8 inch to 1-3/4 inch doors. If a specification or facility standard calls for a commercial Grade 2 storeroom lever with ANSI strike prep, a Grade 3 lever will not satisfy it.

They are not interchangeable where lever operation is required. The Deltana Clarendon CL504EVC is lever trim on a commercial Grade 2 cylindrical lock. Knob options such as the Arrow HK11-BB turn-pushbutton entrance lock with ball knob over 1-3/8 inch to 1-3/4 inch, the Arrow MK02-TA privacy lock with Tudor knob, and the Arrow MK33-BD-CS asylum ball knob all use a knob rather than a lever. ADA accessible openings call for hardware operable without tight grasping or twisting of the wrist, which is why lever trim goes on commercial and public doors.

Three finishes: Oil Rubbed Bronze, Brushed Chrome, and Polished Brass. If you're matching existing openings, brushed chrome reads closest to the satin chrome and 26D-family trim common on commercial doors, and oil rubbed bronze pairs with dark bronze hardware suites.

Removable through-bolts are supplied. Through-bolting clamps the two roses through the door for a stronger fix on a security opening, and because they're removable you can leave them off where the door prep or a narrow stile makes them awkward. No separate mounting kit to order.

Among the cylindrical levers, the Falcon K101 is a Grade 1 heavy duty non-handed passage lock carrying a fire rating and a 1-3/8 inch to 2-1/4 inch door thickness range, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage lever with a fire rating over 1-3/4 inch to 2 inch. Both are passage function, so neither secures the opening. The Deltana Clarendon CL504EVC is the keyed storeroom lever with a UL Listed latch. On a rated opening, confirm the assembly listing against the door and frame label before ordering.

To keep one lever shape across an opening set, pair the keyed Deltana Clarendon CL504EVC storeroom lever with passage levers on the doors that only latch. Grade 2 passage levers include the Accentra 5301LN Augusta from the 5300 series, the Accentra 4601LN with Augusta trim from the 4600 series, the Hager 2510 with the Withnell lever over 1-3/8 inch to 2 inch, and the Bravura Atlanta, Orlando, and Tampa round and square trim leversets. Matching lever families across a floor is a trim decision; the keyed door still needs the storeroom function.
