Deltana CL604EVC Commercial Storeroom Standard Grade 2, Curved Lever with Cylinder

As supplied, the CL604EVC comes with a 2-3/4 inch backset latch. A 2-3/8 inch backset latch is sold separately, so if your doors are bored at 2-3/8 inches you need to order that latch along with the lockset. Most commercial openings run 2-3/4 inches, most residential-style preps run 2-3/8.

It covers 1-3/8 inch through 2 inch doors, so it handles both standard 1-3/4 inch commercial doors and thinner 1-3/8 inch older interior doors without extra parts. Removable through-bolts are included for mounting.

Storeroom function on the CL604EVC means the outside lever is always locked and only the key retracts the latch. The inside lever always turns for free egress, and there is no button or thumbturn to leave the door unsecured. That is why it suits storage rooms, mechanical rooms, electrical closets and IT rooms where the door must never be left unlocked by accident.

The cylinder is a Schlage C keyway, so it can be keyed alike or keyed into an existing system built on Schlage C. It is a single cylinder lock, keyed outside only. If your building runs a different keyway, this one will not pin to it.

It ships with a T-strike measuring 2-3/4 by 1-3/4 inches and the latch is UL Listed with a 1/2 inch throw. If your frame already has an ANSI-type or T-strike cutout of those dimensions, the supplied strike drops in; a deeper or differently shaped existing strike pocket may need filling or a different strike plate.

The Hager 2580 with the Withnell lever is the closest match: it is a Grade 2 cylindrical storeroom lock with a 1-3/8 inch to 2 inch door thickness range, the same range the Deltana CL604EVC covers. The Cal-Royal AG05 is also a Grade 2 storeroom lever lockset with a deadlocking latchbolt, covering 1-3/8 inch to 1-3/4 inch doors. All three give the storeroom function where the outside lever is always locked and the key retracts the latch.

Storeroom function on the Deltana CL604EVC keeps the outside lever locked at all times, so entry always requires the key. For an opening that needs to be unlocked during the day, the Hager 2525 is a Grade 2 cylindrical entry lock with a lever handle for 1-3/8 inch to 2 inch doors, and the Falcon B511CP6D is a Grade 2 lever lock with entry/office function. Cal-Royal's AG00 entrance lever uses a 6-pin Schlage C keyway with a 2-3/8 inch backset.

The Deltana CL604EVC is a Grade 2 commercial cylindrical lever lock. For Grade 1 cylindrical lever locks in the same bored-lock format, the Dexter C1000 series is Grade 1 and includes classroom, classroom security, and asylum functions across 1-3/8 inch to 2 inch doors on the asylum version, and Falcon's K series K101 is a Grade 1 heavy duty cylindrical lock with a 1-3/8 inch to 2-1/4 inch door range and a fire rating. Corbin Russwin's CL3100 series is Grade 1 and vandal resistant for 1-3/4 inch to 2 inch doors.

The Deltana CL604EVC uses a Schlage C type keyway. Cal-Royal's AG00 entrance lever and AG03 classroom lever both use a 6-pin Schlage C keyway keyed different, and the Arrow MK33-BD-CS is a Grade 2 asylum cylindrical lock with a conventional cylinder in Schlage C keyway. On the Yale/Accentra side, the 107S is a Schlage cylinder adapter kit that lets Yale hardware take a Schlage cylinder.

No handing to call out. The CL604EVC is universal, so the same lockset works on a left or right hand door and one part number covers every opening in a building. That simplifies stocking for a property manager carrying spares.

Grade 2 is the standard commercial duty level and the CL604EVC is built for commercial use with a steel and zinc chassis. For moderate traffic storage, utility and back-of-house doors it is the normal spec. For high-abuse openings such as main entries or school corridors, step up to a Grade 1 cylindrical lock like the Dexter C1000 Series or the Falcon K Series.

Not really. Storeroom function keeps the outside lever locked at all times, which is wrong for a room people need to walk into freely during the day. For an office you want entry/office function, such as the Falcon B511CP6D or Hager 2525. For a classroom, the Cal-Royal AG03 classroom lever or the Dexter C1000 classroom lock is the correct function.

Yes, if the opening never needs to be secured, a non-keyed passage lever is the right part instead of the keyed storeroom CL604EVC. Grade 2 options include the Hager 2510 passage lever for 1-3/8 inch to 2 inch doors, the Accentra 5301LN Augusta passage/closet lever, the Falcon B101 medium duty non-handed passage lever, and the Arrow GL01 Sierra lever for 1-3/4 inch to 2 inch doors. None of these accept a key, so they are not a substitute anywhere access control is required.

No. The Deltana CL604EVC is storeroom function, where the outside lever stays locked and the key only retracts the latch for entry. A classroom lever such as the Cal-Royal AG03, a Grade 2 classroom lever with a 2-3/4 inch backset and 6-pin Schlage C keyway, lets the key lock and unlock the outside lever so it can be left unlocked while the room is occupied. Dexter's C1000 classroom and classroom security levers are the Grade 1 versions of that function. Specify by function, not by appearance, since the trim looks identical.

The Deltana CL604EVC is a key-operated single cylinder storeroom lock. To drop keys entirely, the Delaney LP250 is an electronic keypad leverlock rated Grade 2, and the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination covering 1-1/8 inch to 2 inch doors, with the 1150S adding an adjustable backset. The Lockey 2835 is a mechanical pushbutton keyless lever for 1-3/16 inch to 2 inch doors. These are passage-function keypad sets, so confirm the locking behavior matches what the storeroom door needs.

The Deltana CL604EVC is a commercial Grade 2 cylindrical lever with a steel and zinc body, intended for commercial traffic. Grade 3 levers such as the Cal-Royal AUS00 entrance/office lever for 1-3/8 inch to 1-3/4 inch doors, the Callan Artino entrance leverset, and the Master Lock RL series keyed entry lever are built to a lighter ANSI/BHMA cycle and strength rating. For common-area, utility, and storage doors in multi-family, the Grade 2 commercial lock is the closer match to the duty the opening sees.

Two finishes: Oil Rubbed Bronze and Brushed Chrome. If you are matching existing hardware across a building, brushed chrome reads closest to the satin chrome and satin nickel trim common on commercial openings, while oil rubbed bronze suits darker residential-style or hospitality interiors.

It is a bored cylindrical lockset with a tubular lock type, the standard 2-1/8 inch bore style installation used on commercial doors. Removable through-bolts hold the roses, which is what lets a maintenance tech pull and re-secure the trim without special tools.

The CL604EVC is a working keyed storeroom lockset, so an inactive leaf needs a separate dummy trim. Non-keyed dummy options include the BEST 7KC single dummy trim in Grade 2 medium duty, the BEST 9K 1DT single dummy trim in Grade 1 heavy duty, the Accentra 455LN Augusta Grade 1 single dummy, and the Callan Bentley Grade 2 dummy lever. Dummy trim has no latch and is surface mounted, so lever style and finish are what you match on, not the bore.

Storeroom function on the CL604EVC requires a key from outside and has no thumbturn. For a restroom or similar opening that needs an inside privacy turn instead, the Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors, and the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob, non-keyed and fire rated, for 1-3/4 inch to 2 inch doors. Privacy sets are not keyed, so they do not provide the access control a storeroom lock does.
