Dexter C2000 Series - Grade 2 Classroom Cylindrical Lever Lock, Non-Clutching, Keyed

Both. The C2000 Series cylindrical lever lock covers a 1-3/8 inch to 1-3/4 inch door range as standard, so it works on older 1-3/8 inch interior openings and on standard 1-3/4 inch commercial doors without a spacer kit or a different chassis. Anything thicker than 1-3/4 inches is outside the range.

It ships with the C2000-ACLS strike, an ANSI 1-1/4 inch x 4-7/8 inch curved lip strike, which is the full-lip ANSI prep most commercial hollow metal frames are cut for. If your frame is cut for that ANSI opening, the lock lands in it. If the frame has a smaller T-strike cutout, you will need to enlarge the prep or reuse a strike that suits the existing mortise. The latch faceplate measures 1 inch x 2-1/4 inch.

Classroom function, ANSI/BHMA F84. The outside lever is locked and unlocked by key from the outside only; there is no thumbturn or pushbutton on the inside, so a student cannot lock the room and the inside lever always retracts the latch for free egress. That is what makes it a classroom lock rather than an entry or office lock. If you want staff to be able to lock the door from inside the room without a key, this is the wrong function.

The C2000 Series cylindrical locks are UL listed for 3 hours, which covers fire door assemblies up to a 3 hour rating. The classroom function has no inside locking device, so the inside lever retracts the latch in one motion for egress.

The conventional cylinder option (KDC) is a 6-pin Schlage C cylinder, keyed different as supplied, so it sits on the same keyway as an existing Schlage C system. The chassis also accepts small format interchangeable core, 6-pin or 7-pin, if your building is on an SFIC system.

Two cylinder choices. KDC gives you a complete lock with a conventional 6-pin Schlage C cylinder, keyed different, ready to hang. SFIC Prep Less Core arrives with the core cavity only, no core in it, for a facility that buys and pins its own interchangeable cores (6-pin or 7-pin). Order SFIC only if you already have cores; otherwise the door will not lock when it arrives.

The Cal-Royal AG03 is the nearest match. It is a classroom function lever in the AG Series with a Grade 2 rating, a 6-pin Schlage C keyway keyed different, and a 2-3/4 inch backset - the same classroom function, the same Schlage C 6-pin conventional cylinder, and the same 2-3/4 inch backset the Dexter C2000 classroom lever carries as standard. Both are non-clutching cylindrical levers for commercial openings.

Order a storeroom function lever. The Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt and a 1-3/8 to 1-3/4 inch door thickness range, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for doors 1-3/8 to 2 inches thick. A storeroom lever keeps the outside lever locked at all times and is retracted by key only; the classroom function on the Dexter C2000 is locked and unlocked by key from the outside so the teacher can leave the room in passage.

Several cylindrical levers share the same trim look and the same 161 door prep but have no cylinder at all. The Falcon B101 is a Grade 2 medium duty passage lever, the Accentra 5301LN Augusta is a Grade 2 passage/closet lever in the 5300 Series, and the Hager 2510 is a Grade 2 passage lever with the Withnell design for doors 1-3/8 to 2 inches thick. Passage levers turn freely from both sides and never lock. The Dexter C2000 classroom lever is keyed, single cylinder, so a key on the outside secures the opening.

Look at the Corbin Russwin CL33903 electrified cylindrical lever, a Grade 1 fail safe lever running on 12VAC/DC in the CL33900 Series for doors 1-3/4 to 2 inches thick. Fail safe means the lever unlocks when power drops, which suits a door tied to a fire or lockdown system. The Dexter C2000 classroom lever is purely mechanical, keyed with a single cylinder, and needs no wiring or door prep for power transfer.

The Dexter C2000 classroom lever covers 1-3/8 to 1-3/4 inch doors as standard. For a thicker leaf, the Falcon K101 Grade 1 passage lever covers 1-3/8 to 2-1/4 inches, the Corbin Russwin CL3110 Grade 1 vandal resistant passage/closet lever covers 1-3/4 to 2 inches, and the Hager 2525 Grade 2 entry lever covers 1-3/8 to 2 inches. Note the Falcon and Corbin Russwin options named here are passage function and do not lock.

Besides the Dexter C2000 classroom lever, which ships with a 6-pin Schlage C conventional cylinder keyed different, the Cal-Royal AG03 classroom lever and the 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 Schlage C keyway cylinder. Any of these can be rekeyed into an existing Schlage C system by a locksmith.

The Dexter C2000 classroom lever can be ordered with an SFIC prep less core, accepting a 6-pin or 7-pin small format interchangeable core. Among the alternatives, the BEST 7KC Series and 9K Series cylindrical levers are the interchangeable core families, though the 7KC 1DT and 9K 1DT are single dummy trims with no latch. For a keyed classroom opening on an SFIC system, the C2000 with the SFIC prep is the direct route.

Non-handed. One lock covers a left or right hand door, so you do not specify handing on the order and you can stock a single part for a building with openings swinging both ways. The lever design choice (curved or regular) is a trim style decision, not a handing one.

Grade 2 is the mid-duty commercial tier and the C2000 is rated commercial, which suits classroom and office doors on normal traffic. For a high-abuse opening (a main corridor, a gym, a public restroom) a Grade 1 cylindrical is the heavier chassis. In that tier ZenSupply carries the Corbin Russwin CL3100 Series, which is Grade 1, fire rated, and specified for 1-3/4 inch to 2 inch doors, and the Falcon K Series, Grade 1 heavy duty and fire rated for 1-3/8 inch to 2-1/4 inch doors. Note both of those examples are non-keyed passage; match the function when you cross over.

No. Classroom function leaves the outside lever unlocked until someone keys it locked, which is wrong for a storage or equipment room that should stay secure at all times. For those doors use a storeroom function, where the outside lever is always locked and the key retracts the latch. ZenSupply carries the Cal-Royal AG05, a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors, and the Hager 2580 Grade 2 storeroom lock with the Withnell lever for 1-3/8 inch to 2 inch doors.

Both are included. The lock ships with the C2000-SD-234 deadlatch, 2-3/4 inch backset and 1 inch diameter, and the C2000-ACLS ANSI curved lip strike. The only thing you choose is which backset latch comes in the box, since backset is a required selection at order. Nothing further is needed to hang the lock on a correctly prepped door.

The C2000 is a bored cylindrical chassis on a 2-3/4 inch backset with a 1 inch x 2-1/4 inch latch faceplate and an ANSI 1-1/4 inch x 4-7/8 inch strike, and it is non-handed. Doors prepped that way take any C2000 function, so classroom on teaching spaces and other functions elsewhere all share the same door prep, strike prep and Schlage C keyway. That is what makes a fleet standardization work: one prep, one keyway, one spare-parts list.

For heavy duty cylindrical levers, the Falcon T101 is a Grade 1 heavy duty lever in the T Series with pressure release technology, and the Falcon K101 is a Grade 1 heavy duty lever rated for doors 1-3/8 to 2-1/4 inches thick. Both are passage function, so they carry no cylinder - on a door that has to lock, the Dexter C2000 classroom lever is the keyed option, at Grade 2 with a Schlage C 6-pin cylinder.

Yes - an entrance or entry/office function lever. The Falcon B511CP6D is a Grade 2 medium duty entry/office cylindrical lever, the Hager 2525 is a Grade 2 commercial entry lever for doors 1-3/8 to 2 inches, and the Cal-Royal AG00 is an entrance lever with a 6-pin Schlage C keyway keyed different on a 2-3/8 inch backset. Entry/office locks are usually set by a pushbutton or turn on the inside; the Dexter C2000 classroom lever is locked and unlocked from the outside by key only, with no inside locking button.

For keyless entry on a lever, the Delaney LP250 is a Grade 2 electronic keypad leverlock, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for doors 1-3/16 to 2 inches thick, and the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination for doors 1-1/8 to 2 inches. These are code-entry rather than key-entry; the Dexter C2000 classroom lever uses a 6-pin Schlage C conventional cylinder or an SFIC prep taking a 6-pin or 7-pin core, so it can join an existing keyway or an interchangeable core system.

Grade 3 levers such as the Kwikset 200BRNL Breton passage lever for 1-3/8 to 1-3/4 inch doors, the Master Lock BC Series RL01 keyed entry lever, and the Callan Artino entrance leverset are built to a lighter cycle and strength standard. The Dexter C2000 classroom lever is a commercial Grade 2 cylindrical lock meeting ANSI/BHMA F84 and UL listed 3 hour, which is what a specification for a classroom or rated corridor door normally calls for.

A dummy trim has no latch and no cylinder - it mounts as a pull only. The BEST 7KC Series 1DT is a Grade 2 medium duty single dummy trim cylindrical lever, the BEST 9K Series 1DT is the Grade 1 heavy duty equivalent, and the Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever in the 5400 Series. Pair the dummy to the active leaf keyed lever so the two leaves read as one set.

Three: 605 bright brass, 613 oil-rubbed bronze, and 626 satin chrome. All three are available with either lever design and with either cylinder option, so a satin chrome SFIC prep or an oil-rubbed bronze conventional cylinder are both orderable combinations. 626 is the usual choice when you are matching existing commercial hardware in a school or office.

Non-clutching means the outside lever stays mechanically tied to the chassis when the lock is keyed locked, so it does not spin free under force. A clutching lever turns freely when locked and absorbs abuse instead of passing it to the chassis. On a classroom door where the lever is locked only when the room is in use, non-clutching is normal; on a heavily abused opening a clutching or vandal resistant chassis, like the Corbin Russwin CL3100 Series, holds up better.

For a knob trim on a commercial cylindrical lock, the Arrow HK11-BB is a turn-pushbutton entrance lock with a ball knob and conventional cylinder for doors 1-3/8 to 1-3/4 inches, and the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob, non-keyed and fire rated. Where the opening needs ADA compliant operation, the Dexter C2000 uses a lever handle, non-handed, in curved or regular designs.
