Dexter C1000 Series - Grade 1 Classroom Cylindrical Lever Lock, Clutching, Keyed

Classroom function on the C1000: the outside lever is locked and unlocked only by key from the outside. The inside lever always retracts the latch for free egress, and there is no inside button or turn, so nobody can lock the door from inside the room. It is the ANSI/BHMA F84 function, single cylinder keyed.

The C1000 comes with the C1000-ACLS ANSI strike, 1-1/4 x 4-7/8 inches with a curved lip. If your frames are already cut for the ANSI 4-7/8 strike, which is standard on hollow metal commercial frames, the new lock drops into the same cutout. Frames with a small T-strike or a round-corner residential strike will need the opening modified or a different strike.

Yes, order the SFIC Prep Less Core version. It is prepped for small format interchangeable cores and accepts 6-pin or 7-pin cores, which you supply and key into your existing system. If you would rather have the lock arrive keyed and ready, the KDC option ships with a conventional 6-pin Schlage C cylinder, keyed different.

The conventional cylinder version uses the Schlage C keyway with a 6-pin cylinder, so it belongs to the same keyway family most commercial buildings are already running. It ships keyed different, meaning each lock has its own key out of the box, so a locksmith will need to rekey them to your system or your master pinning.

The C1000 Series is Grade 1 and UL listed for 3 hour openings, so it can go on a fire rated classroom or corridor door. The classroom function keeps the inside lever always free, which is what fire and egress inspections look for on an occupied room.

The Cal-Royal AG03 is a classroom-function lever with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset, which matches the Dexter C1000 classroom lock's 2-3/4 inch backset and its Schlage C 6-pin keyed different cylinder option. The Cal-Royal AG03 is listed as a Grade 2 classroom lever, while the Dexter C1000 is Grade 1, so the Cal-Royal suits interior classroom or office doors where Grade 1 cycle testing is not written into the spec.

Classroom and storeroom are different functions and are not interchangeable: the Dexter C1000 classroom lock is an F84 classroom function, where the outside lever is locked and unlocked by key and stays in whichever state the key left it. For a storeroom opening where the outside lever is always locked and the key retracts the latch, the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for doors 1-3/8 to 1-3/4 inches thick, or the Hager 2580 is a Grade 2 storeroom lever with the Withnell lever for doors 1-3/8 to 2 inches.

The Dexter C1000 classroom lever is a keyed Grade 1 cylindrical lockset. For the passage and closet doors in the same run, Grade 1 non-keyed cylindrical levers include the Falcon K101, a Grade 1 heavy duty passage lock with non-handed levers, fire rated, for doors 1-3/8 to 2-1/4 inches; the Falcon T101, a Grade 1 heavy duty passage lever; the Corbin Russwin CL3110 Grade 1 vandal resistant passage/closet lever for 1-3/4 to 2 inch doors; and the Design Hardware X75 Grade 1 passage lever with a flat lever for 1-3/4 inch doors. For a door that needs trim only with no latch, the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim.

The Dexter C1000 classroom lever is specified for doors 1-3/8 to 1-3/4 inches thick. For a 2 inch door, cylindrical levers rated to that thickness include the Falcon K101 Grade 1 passage lock at 1-3/8 to 2-1/4 inches, the Corbin Russwin CL3110 Grade 1 passage/closet lever at 1-3/4 to 2 inches, and the Hager 2525 Grade 2 entry lever at 1-3/8 to 2 inches. Note those are passage and entry functions, not classroom, so confirm the function the opening calls for before substituting.

No. The Dexter C1000 is an F84 classroom function, keyed on the outside with no inside pushbutton, so occupants cannot lock the door from within the room. Entrance and office levers such as the Falcon B511CP6D Grade 2 entry/office lever, the Hager 2525 Grade 2 commercial entry lever, or the Cal-Royal AG00 Grade 2 entrance lever with a 6-pin Schlage C keyway and 2-3/8 inch backset lock and unlock from the inside as well. Note the Cal-Royal AG00 is a 2-3/8 inch backset against the Dexter C1000's 2-3/4 inch, so the existing door prep matters when swapping.

No handing to specify. The C1000 cylindrical lever is non-handed, and the beveled deadlatch works either swing, so one part number covers left and right hand openings. That is useful if you are stocking spares for a building with doors swinging both ways.

When the outside lever is locked, a clutching lever spins free instead of holding rigid. Force applied to the handle, someone yanking or hanging on it, goes nowhere near the internal lock mechanism. In school corridors, dorms, and other high abuse traffic that is the single biggest cause of lockset failure, so the clutching design is the reason to spec the C1000 over a non-clutching lever.

The Dexter C1000 classroom lever is key-operated with a 6-pin Schlage C conventional cylinder or an SFIC prep less core. If you would rather manage access by code, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for doors 1-3/16 to 2 inches, the Lockey 2835DC adds double combination, and the Lockey 1150 is a heavy duty mechanical keypad lever set for doors 1-1/8 to 2 inches. For an electronic option, the Delaney LP250 is a Grade 2 electronic keypad leverlock. These are code-credentialed and do not carry the Dexter's Grade 1 classroom function, so they suit rooms where key control rather than classroom lockdown is the goal.

The Dexter C1000 classroom lever is a mechanical key-operated cylindrical lockset with no electrified option. For an opening that has to change state on a signal, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running on 12VAC/DC for doors 1-3/4 to 2 inches thick. That requires power to the door and a door thickness above the Dexter C1000's 1-3/8 to 1-3/4 inch range, so it is a different scope of work, not a drop-in.

The Dexter C1000 is a lever-handle cylindrical lock, which is what ADA-governed openings generally call for. Knob-style cylindrical locks in comparable functions include the Arrow HK11-BB turn-pushbutton entrance lock with a ball knob and conventional cylinder for doors 1-3/8 to 1-3/4 inches, and the Arrow MK33-BD-CS heavy duty asylum-function ball knob lock with a conventional Schlage C keyway cylinder. Those are knob trim, so check the accessibility requirements for the facility before substituting one for a lever.

The Dexter C1000 is a keyed classroom lock and is not a privacy function. For restrooms and similar openings, the Hager 2540 is a Grade 2 cylindrical privacy lock with the Withnell lever for doors 1-3/8 to 2 inches, and the Arrow MK02-TA is a non-keyed privacy cylindrical lock with a tudor knob and a fire rating. The Hager keeps a lever handle consistent with the Dexter; the Arrow is knob trim.

The Dexter C1000 is a Grade 1 commercial cylindrical lock, UL listed 3 hour, with a 2-3/4 inch backset and an ANSI 1-1/4 by 4-7/8 inch curved lip strike. Levers such as the Kwikset 200BRNL Breton passage set and the Kwikset 300BRNL Breton privacy set are Grade 3 for doors 1-3/8 to 1-3/4 inches, and the Master Lock BC Series RL01 is a Grade 3 keyed entry lever. Those are built for residential-duty openings and do not offer a classroom function, so they are not a substitute where a Grade 1 classroom lock is specified.

Two finishes, 613 oil-rubbed bronze and 626 satin chrome, and two clutching lever shapes, curved and regular. All four combinations are available with either the Schlage C conventional cylinder or the SFIC prep. Satin chrome 626 is the usual pick when you are matching existing commercial door hardware in a school or office.
