Deltana CL509EVC Commercial Classroom Standard Grade 2, Clarendon Lever with Cylinder

Yes. The CL509EVC Clarendon classroom lever covers doors from 1-3/8 inch up to 2 inch thick, so it handles both older 1-3/8 interior doors and standard 1-3/4 commercial doors without a thickness kit.

It ships with the 2-3/4 inch backset. The 2-3/8 inch backset is sold separately, so if your existing cross bore is 2-3/8 from the door edge you need to add that latch to the order.

The latch is UL Listed with a 1/2 inch throw and the lock uses an ANSI 4-7/8 x 1-1/4 inch strike. If your frame already has ANSI strike prep, it drops in. If you have a small residential T-strike or a full-lip 2-3/4 inch strike, you will be filling and re-prepping the jamb.

No. The Clarendon CL509EVC is universal handed, so one part number covers left and right hand doors. That is useful for a property manager stocking spares across a building.

The cylinder is a Schlage C type keyway, so it can be keyed alike or mastered into an existing Schlage C system by your locksmith. It is a single cylinder keyed function, meaning key access from the outside only.

The Cal-Royal AG03 is the nearest match: it is a Grade 2 classroom lever with a 6-pin Schlage C keyway, keyed different, on a 2-3/4 inch backset, which lines up with the CL509EVC's classroom function, Schlage C type keyway and 2-3/4 inch backset. Both are keyed cylindrical lever locks intended for commercial openings, so a school or office standardized on Schlage C keying can cross between them without changing key systems.

The Dexter C1000 Series classroom lever is the step up: it is a Grade 1 keyed cylindrical lever with clutching levers, rated for doors 1-3/8 to 1-3/4 inch thick. The CL509EVC is a Grade 2 commercial classroom lever in steel and zinc fitting doors 1-3/8 to 2 inch. If the corridor spec calls for ANSI/BHMA Grade 1 or you want a clutching lever that spins free under abuse, the C1000 classroom meets it; the CL509EVC covers a wider door thickness range.

No. The CL509EVC is a classroom function lock with a single cylinder, keyed from the outside only. For inside-the-room lockdown you want a classroom security function, which has a cylinder on both sides so a teacher can lock the outside lever without stepping into the corridor. The Dexter C1000 Series classroom security lever is the Grade 1 keyed cylindrical option for that, with clutching levers and a 1-3/8 to 1-3/4 inch door thickness range.

On the CL509EVC, the key on the outside locks and unlocks the outside lever. There is no button or turn on the inside, so the door cannot be accidentally locked from within the room, and the inside lever always retracts the latch for free egress. That is the standard classroom behaviour schools and institutions specify.

Grade 2 is the standard commercial duty level and suits moderate traffic offices, classrooms and multi-family corridors. For high abuse openings, a Grade 1 classroom lever like the Dexter C1000 Series classroom lock is the heavier option, though it covers 1-3/8 to 1-3/4 inch doors rather than up to 2 inch.

Yes, the Cal-Royal AG03 classroom lever is a Grade 2 lock with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, which is the same backset the Deltana Clarendon ships with. Either can be keyed into the same Schlage C system.

The CL509EVC is a keyed classroom lock only. For passage or dummy openings in the same building, Grade 2 non-keyed options include the Hager 2510 passage lever, which covers the same 1-3/8 to 2 inch door thickness range, and the BEST 7KC Series single dummy trim. Trim styling will not match the Clarendon, so match by finish.

For a corridor or closet door that just needs latching, a passage lever skips the cylinder entirely. Grade 2 passage options include the Hager 2510 Withnell lever for doors 1-3/8 to 2 inch, the Falcon B101 medium duty non-handed passage lever, and the Accentra 5301LN Augusta from the 5300 Series. The CL509EVC by contrast is a keyed classroom lock with a Schlage C type cylinder.

A storeroom function fits better there: the outside lever stays locked at all times and a key retracts the latch, so the door is never left unsecured. Grade 2 storeroom levers include the Hager 2580 with Withnell lever for doors 1-3/8 to 2 inch and the Cal-Royal AG05 with a deadlocking latchbolt. The CL509EVC is a classroom function, where the outside lever is locked and unlocked by key and can be left free.

They are not interchangeable by function. The AG00 is an entrance lever with a 6-pin Schlage C keyway keyed different on a 2-3/8 inch backset, for doors 1-3/8 to 1-3/4 inch. The CL509EVC is a classroom function on a 2-3/4 inch backset for doors 1-3/8 to 2 inch. Both share the Schlage C keyway, so they can live on one key system, but an entrance lock has an inside button or turn that locks the outside lever, while classroom function is key-controlled from the outside only.

Keyless lever sets trade the cylinder for a code. The Delaney LP250 is a Grade 2 electronic keypad leverlock, and the Lockey 2835 is a mechanical pushbutton keyless lever with passage function and ADA compliance for doors 1-3/16 to 2 inch. Note that the Lockey 2835 is a passage-style keyless unit, so it does not provide the key-controlled classroom function the CL509EVC does with its Schlage C type cylinder.

Yes, the CL509EVC covers 1-3/8 through 2 inch doors. Peers rated to 2 inch include the Hager 2510 Grade 2 passage and Hager 2525 Grade 2 entry levers at 1-3/8 to 2 inch, the Arrow GL01 Grade 2 passage at 1-3/4 to 2 inch, and the Corbin Russwin CL3110 Grade 1 passage at 1-3/4 to 2 inch. Of those, only the CL509EVC is a keyed classroom function.

No. The CL509EVC is a single cylinder classroom lock, keyed on one side. Asylum or institutional function keys both sides with no free lever, and the Dexter C1000 Series asylum F87 is the Grade 1 option for doors 1-3/8 to 2 inch. The Arrow MK33-BD-CS is a Grade 2 asylum function with a conventional cylinder in the Schlage C keyway, which matches the CL509EVC keyway if you are keying a facility alike.

Three: Oil Rubbed Bronze, Brushed Chrome and Polished Brass. If you are matching existing openings, Oil Rubbed Bronze and Polished Brass suit traditional trim while Brushed Chrome reads closer to typical commercial satin hardware.

It is a tubular cylindrical lockset with removable through-bolts, so the roses fasten through the door for a tighter hold and can be taken off for service. Body construction is steel and zinc.

Use a dummy lever, which is trim only with no latch. Grade 2 dummy options include the BEST 7KC Series single dummy trim, a medium duty non-keyed cylindrical lever, and the Callan Bentley dummy lever; for a Grade 1 pairing the BEST 9K Series 1DT single dummy trim is heavy duty and non-keyed. None of these latch or key, so they only suit a door that does not need to secure, unlike the keyed classroom CL509EVC.

Grade 3 levers sit below it. The Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body for doors 1-3/8 to 1-3/4 inch, the Master Lock BC Series RL01 is a Grade 3 keyed entry return-style lever, and the Callan Artino is a Grade 3 entrance leverset. The CL509EVC is a Grade 2 commercial classroom lock in steel and zinc.

They serve different openings. The Baldwin Estate 5103 with 5048 rose is offered in passage, privacy, and half dummy versions, the dummy handed left or right, and is a residential-style decorative trim. The CL509EVC is a commercial Grade 2 keyed classroom lever in steel and zinc with a universal handing latch and an ANSI 4-7/8 by 1-1/4 inch strike, so it drops into a standard commercial strike prep and is key controlled.
