Corbin Russwin CL3855 PZD 626 LC – Frequently Asked Questions

1) How does a classroom function lock actually work when the teacher locks the door?

On the CL3855, the outside lever is locked and unlocked only by key from the outside. Once locked, the outside lever freewheels, it turns but does nothing, so nobody can force it. The inside lever is always free, so anyone in the room can get out at any time without a key. The latchbolt is deadlocking, meaning it resists being carded or shimmed once the door is closed. Practical consequence for a school: staff cannot lock the door from inside the room, they have to step into the corridor with the key. If you need lockdown from inside the classroom, you want a classroom security function instead, such as the Dexter C1000 Series Classroom Security lever.

2) Can the Corbin Russwin CL3855 go on a fire rated door?

Yes. The CL3855 is UL and cUL listed for 3 hour fire doors up to 4 feet by 10 feet, and the lock is listed to NFPA 80. It also meets ADA A117.1 for operable hardware, which is what the lever shape buys you over a knob. Grade is ANSI/BHMA A156.2 Series 4000, Grade 2, and the function is ANSI F84.

3) What cylinder and keyway does the Corbin Russwin CL3855 come with, and can I put it on my existing key system?

Standard is a conventional 6-pin brass cylinder in the Corbin Russwin L4 keyway, shipped 0-bitted so a locksmith can pin it to your system. If you run interchangeable core, order it CL6 for a 6-pin Corbin Russwin LFIC less core, or CL7 for 7-pin LFIC less core, then drop your own cores in. If you already have cylinders on the shelf or your integrator supplies them, order LC (less conventional cylinder) and fit your own. Keyed different is standard, keyed alike is available when you want one key across a run of doors.

4) What is a Grade 1 classroom lever lock alternative to the Corbin Russwin CL3855?

The Dexter C1000 Series classroom cylindrical lever lock is a Grade 1 keyed classroom lever with a clutching lever design, covering doors 1-3/8 inch to 1-3/4 inch. The Corbin Russwin CL3855 is a Grade 2 classroom lever, also non-handed and keyed, for doors 1-3/8 inch to 1-3/4 inch. Both fit the same classroom function on the same door thickness range; the Dexter carries the higher ANSI/BHMA grade for openings where a Grade 1 lock is called out on the drawing.

5) Is there another Grade 2 classroom lever lock with the same 2-3/4 inch backset as the CL3855?

The Cal-Royal AG03 is a Grade 2 classroom lever with a 2-3/4 inch backset and a 6-pin Schlage C keyway supplied keyed different. The Corbin Russwin CL3855 also uses a 2-3/4 inch backset as standard, but ships with a conventional 6-pin cylinder in the L4 keyway. The backset prep is the same, so the difference for a locksmith is the keyway family the opening has to key into.

6) Does the CL3855 lever lock need to be ordered left hand or right hand?

No handing to specify. The CL3855 is non-handed, and the spring cassette inside is non-handed too, which is what keeps the lever from sagging over time. One part number covers left and right hand doors, so a property manager stocking spares only needs one line item.

7) What lever styles and finishes does the Corbin Russwin CL3855 come in?

Three lever designs: AZD Armstrong, NZD Newport and PZD Princeton, all solid cast with no plastic inserts. Fourteen finishes, from 605 bright brass and 606 satin brass through 611 and 612 bronze, the 613 oil-rubbed bronze family including 613E and 613L, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 722 black oxidized bronze, plus BSP black suede and WSP white suede powder coat. If you are matching existing openings in a building, 626 satin chrome with the Newport lever is the usual configuration.

8) Is a Grade 2 lever lock enough for a school corridor, or should I spend up to Grade 1?

Grade 2 medium duty is the right call for classroom doors, offices, closets and multi-family unit doors, traffic that is steady but not abusive. The CL3855 helps its case with thrubolts that stop the chassis rotating and solid cast levers, and the Lever Release freewheeling design means a kick or a hang on a locked lever loads a clutch instead of the chassis. Where the door sees genuine abuse, a main entrance, a stairwell, a gym, go Grade 1 heavy duty instead: the Dexter C1000 Series Grade 1 classroom lever is the direct equivalent function in a heavier chassis and covers the same 1-3/8 to 1-3/4 inch doors.

9) Which latch face do I order if my existing doors have a rounded latch mortise?

Two latch faces are available on the CL3855, both 2-1/4 x 1-1/8 inches on a 2-3/4 inch backset. The 600F10 square corner is standard; the 600F13 has rounded corners. Match whichever is cut into your door edge now and you avoid routing the mortise. Rounded corner faces are typical on doors prepped by machine, square corner on hand-mortised work.

10) Is the Hager 2580 a substitute for the Corbin Russwin CL3855 classroom lock?

Not on function. The Hager 2580 is a Grade 2 storeroom cylindrical lock with a Withnell lever, fitting doors 1-3/8 inch to 2 inch, so its outside lever remains locked at all times. The Corbin Russwin CL3855 is a Grade 2 classroom lock whose outside lever is locked and unlocked by key from outside, with the inside lever always free. The Hager 2580 is the match when the opening is a storeroom or a secured utility room, not a classroom that gets unlocked for the day.

11) What is the difference between the Corbin Russwin CL3855 and a storeroom lever like the Cal-Royal AG05?

Both are Grade 2 cylindrical lever locksets with a deadlocking latchbolt, and both suit doors 1-3/8 inch to 1-3/4 inch. The difference is function. The Corbin Russwin CL3855 is a classroom lock, where the outside lever is unlocked by key and stays unlocked until keyed again. The Cal-Royal AG05 is a storeroom function, where the outside lever is always locked and the key retracts the latch for entry. Choose by whether staff need the room left in a passage state between periods.

12) If a door next to a classroom only needs to latch and never lock, what pairs with the CL3855?

The Corbin Russwin CL3855 is a keyed classroom lever, so it is more lock than a corridor or closet door needs. For the non-keyed openings in the same run, the Falcon B101 is a Grade 2 medium-duty non-handed cylindrical passage lever, and the Accentra 5301LN Augusta is a Grade 2 passage and closet cylindrical lever from the 5300 Series. Both are the same medium-duty Grade 2 class as the CL3855 and share its non-handed installation.

13) Does the Accentra 4601LN work as a classroom lock like the CL3855?

No. The Accentra 4601LN is a Grade 2 passage cylindrical lever with Augusta trim from the 4600 Series, which means it has no cylinder and cannot be locked. The Corbin Russwin CL3855 is keyed with a conventional 6-pin L4 keyway cylinder and a single-cylinder classroom function. If the room has to be secured at any point, the 4601LN is not an equivalent.

14) What is the keyless alternative to a keyed classroom lever like the CL3855?

The Corbin Russwin CL3855 controls the outside lever with a key in a conventional 6-pin L4 keyway. Where a facility would rather issue a code than a key, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for doors 1-3/16 inch to 2 inch, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Both remove the key system from the opening entirely, so they suit rooms where key control is the maintenance burden.

15) Which lever lock should I use if the door is thicker than the CL3855 covers?

The Corbin Russwin CL3855 is listed for doors 1-3/8 inch to 1-3/4 inch. For a thicker leaf, the Falcon K101 is a Grade 1 heavy-duty non-handed cylindrical passage lock rated for doors 1-3/8 inch to 2-1/4 inch and fire rated, and the Hager 2525 is a Grade 2 commercial cylindrical entry lever for doors 1-3/8 inch to 2 inch. The K101 is a passage function and the 2525 an entry function, so match the one whose locking behavior fits the opening.

16) What is the difference between a classroom lever like the CL3855 and an entrance or office lever?

The Corbin Russwin CL3855 is a classroom lock: only a key on the outside locks or unlocks the outside lever, so an occupant cannot secure or release the door from inside. An entrance or office function puts that control on the inside. The Falcon B511CP6D is a Grade 2 medium-duty cylindrical lever with entry and office function, and the Dexter C1000 entry and office lever is a Grade 1 keyed clutching lever for doors 1-3/8 inch to 1-3/4 inch. Use the entry function on offices where staff set the lock themselves and the classroom function where a keyholder controls it.

17) I need locks for the whole classroom wing, some keyed and some not. What else in the CL3800 range matches?

The CL3855 is the keyed classroom function. For the non-keyed openings alongside it, keeping to Corbin Russwin cylindrical lever locks means the levers, roses and finishes match across the corridor without a visual mismatch, and the same 2-3/4 inch backset prep works on every door. Corbin Russwin also positions the CL3800 with the CL3300 and CL3500 Series on the same job to hold project cost down. If you would rather source the non-keyed doors elsewhere, the Falcon B101 Grade 2 passage lever and the BEST 7KC Series single dummy trim are both medium duty Grade 2 cylindrical levers.

18) Will the CL3855 lever lock hold up in a coastal or high humidity building?

The chassis is built on a steel substrate with a zinc dichromate treatment for corrosion resistance, and the latchbolt is stainless steel. Fronts are wrought brass, bronze or stainless. It is also windstorm and hurricane certified, which matters for Florida and Gulf coast institutional work. For healthcare and other infection-control settings, MicroShield antimicrobial finish options are available in addition to the fourteen standard finishes.

19) Can I use a knob lockset in place of the CL3855 lever lock?

Only where lever operation is not required. The Corbin Russwin CL3855 uses a lever handle, which is what ADA-governed openings call for. Knob options in the same commercial family include the Arrow MK33-BD-CS, a Grade 2 asylum function ball knob lock with a conventional cylinder in the Schlage C keyway, and the Arrow HK11-BB, a Grade 2 turn-pushbutton entrance ball knob lock with a conventional cylinder for doors 1-3/8 inch to 1-3/4 inch. Neither carries the classroom function of the CL3855.

20) What trim matches the CL3855 on a door leaf that does not take a working lock?

The Corbin Russwin CL3855 is a keyed classroom lever on the active leaf. For an inactive leaf or a false door in the same opening, the BEST 7KC Series 1DT single dummy trim is a Grade 2 medium-duty non-keyed cylindrical lever trim, matching the CL3855's Grade 2 medium-duty class, and the BEST 9K Series 1DT is the Grade 1 heavy-duty version of the same dummy trim.

21) Is a Grade 3 residential lever an acceptable substitute for the CL3855?

Not for a commercial opening. The Corbin Russwin CL3855 is a Grade 2 lock designated commercial. Grade 3 levers such as the Cal-Royal AUS00 entrance and office lever for doors 1-3/8 inch to 1-3/4 inch, the Kwikset 200BRNL Breton passage lever for the same thickness range, and the Master Lock RL Series keyed entry lever sit a grade below and none carries a classroom function. They fit light residential doors rather than a scheduled classroom opening.
