    Corbin Russwin CL3155 NZD 626 – Frequently Asked Questions

    1) How does an F84 classroom function lever actually behave on the door?
    The key outside locks the outside lever, and in that locked state the outside lever freewheels instead of resisting force, which is what protects the internals from being torqued. The key outside unlocks it again. The inside lever is always free, so anyone in the room can get out without a key. That is ANSI function F84, and the latchbolt is deadlocking.
    2) Do I have to order the CL3155 handed for a left or right hand door?
    No handing to specify. The CL3155 is non-handed, so one part number works on either swing, which is why it is a straightforward fleet item for a school or campus with mixed openings.
    3) Will this classroom lock latch into the strike prep already in my frame?
    The CL3155 ships with a deadlatch on a 2-3/4 inch backset, square corner front measuring 2-1/4 x 1-1/8 inches, and an ANSI curved lip strike with a 1-1/4 inch lip length. If your frame is prepped for standard ANSI 4-7/8 inch strike and your door bore is on the 2-3/4 backset, it drops in. A door bored at 2-3/8 inch backset will not accept it.
    4) Can I use the CL3155 on a fire rated classroom door?
    Yes, the CL3155 is fire rated, and the deadlocking latchbolt is what a fire door assembly needs to stay positively latched. It is a Grade 1 commercial lock, which is the level normally specified for rated openings in schools and institutional buildings.
    5) What is the closest Grade 1 classroom lever lock equivalent to the Corbin Russwin CL3155?
    The Dexter C1000 Series classroom cylindrical lever lock (DEX-C1000-CLRM) is the nearest match: it is a Grade 1 keyed classroom function cylindrical leverset with a clutching lever. The difference that matters for the opening is door thickness - the CL3155 is built for doors 1-3/4 inch to 2 inch thick, while the Dexter C1000 classroom is listed for 1-3/8 inch to 1-3/4 inch. On a 2 inch door, the CL3155 is the one that covers it; on a 1-3/8 inch door, the Dexter does.
    6) I need a classroom function lever but Grade 2 is acceptable for my building - what else is there?
    The Cal-Royal AG03 is a Grade 2 classroom lever in the AG Series with a 2-3/4 inch backset and a 6-pin Schlage C keyway keyed different. It shares the classroom function and the 2-3/4 inch backset with the Corbin Russwin CL3155, so the door prep is the same. The CL3155 is Grade 1 and ships with a conventional 6-pin cylinder in the Corbin Russwin L4 keyway, so the two will not key into one system without a cylinder change.
    7) Our district wants lockdown capability from inside the classroom - is the CL3155 the right lock?
    No. The Corbin Russwin CL3155 is ANSI F84 classroom function: the outside lever is locked and unlocked by key from the outside only, and the inside lever is always free. A teacher cannot secure the door from inside without stepping into the corridor. For inside-key lockdown, the Dexter C1000 Series classroom security lever (DEX-C1000-CSEC) is a Grade 1 classroom security function cylindrical lever lock, which is the function written for that requirement.
    8) What lever and rose options do I pick to match the other doors in the building?
    Three lever designs are offered on the CL3155: AZ Armstrong, NZ Newport, and PZ Princeton. Roses are C round 2-3/4 inch diameter, D round 3-1/2 inch diameter (standard), E square 3-1/8 inch, or K round 2-3/4 inch. The larger D rose is the usual choice when you need to cover an older, wider prep or wear ring on the door face.
    9) Is a classroom function lever or a storeroom lever right for my room?
    Classroom, like the CL3155, leaves the inside lever always free and lets a keyholder lock or unlock the outside lever with the key, so a teacher can leave the door unlocked all period. A storeroom lock keeps the outside lever locked at all times and the key only retracts the latch momentarily, which suits closets and mechanical rooms instead. Grade 2 storeroom alternatives include the Hager 2580 and the Cal-Royal AG05.
    10) We already use Schlage C keyway throughout the building - does that rule out the CL3155?
    The Corbin Russwin CL3155 ships standard with a conventional 6-pin cylinder in the L4 keyway, and it is also offered less conventional cylinder and less LFIC core in 6-pin and 7-pin, so a cylinder in your existing system can be fitted. If you would rather buy the lock keyed to Schlage C out of the box, the Cal-Royal AG03 classroom lever is supplied with a 6-pin Schlage C keyway keyed different, and the Arrow MK33-BD asylum lock is offered with a conventional Schlage C keyway cylinder.
    11) What should I use on the storage and janitor doors instead of the CL3155?
    Classroom function on a storeroom door leaves the lever unlocked until someone keys it back, which is usually not what you want. For those openings, the Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch thick, and the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for doors 1-3/8 inch to 2 inch. The Corbin Russwin CL3155 stays on the classroom doors themselves.
    12) Which non-keyed lever matches the CL3155 for the corridor and closet doors in the same building?
    For Grade 1 passage openings alongside Corbin Russwin CL3155 classroom doors, the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers and a fire rating, listed for doors 1-3/8 inch to 2-1/4 inch thick. The Falcon T101 is also a Grade 1 heavy duty passage leverset. Both are non-keyed, so no cylinder or keying needs to be specified the way it does on the keyed CL3155.
    13) Can I use a Dexter C1000 asylum lock in place of the CL3155 on a classroom door?
    They are different functions. The Dexter C1000 asylum lock (DEX-C1000-ASYL) is ANSI F87 asylum/institution function, which is keyed on both sides - neither lever operates without a key. The Corbin Russwin CL3155 is ANSI F84 classroom, where the inside lever is always free for egress. On a classroom or any door needing free exit, the F84 CL3155 is the function to specify.
    14) Is a Kwikset or Baldwin lever an acceptable substitute for the CL3155 in a school?
    Not for a classroom door. The Kwikset 200BRNL Breton and 300BRNL Breton are Grade 3 passage and privacy leversets for doors 1-3/8 inch to 1-3/4 inch, and the Baldwin Estate 5103 is offered in passage, privacy and dummy functions - none of them is a keyed classroom lock. The Corbin Russwin CL3155 is a Grade 1 commercial keyed classroom cylindrical lever lock with a fire rating, which is the class of product a school corridor door is specified with.
    15) What finishes does the CL3155 classroom lever come in?
    Twelve: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 722 black oxidized bronze oil-rubbed, BSP black suede, and WSP white suede powder coat. For schools standardizing, 626 satin chrome is the common institutional match.
    16) How is the CL3155 built to hold up in a high-traffic corridor?
    Internals are steel, zinc dichromated for corrosion resistance, and the lock is Grade 1 cylindrical, the heaviest ANSI duty level for a bored lockset. In the locked state the outside lever freewheels, so someone hanging on the handle is not loading the retractor.
    17) How many keys come with the CL3155?
    Two nickel silver keys ship with the conventional 6-pin L4 keyway cylinder. If you order a CL6 or CL7 less-core version, or the LC less-cylinder version, no keys are supplied because you are fitting your own cores.
    18) I need matching inactive trim on a pair of doors where one leaf takes the CL3155 - what dummy lever do I use?
    A dummy trim has no latch and no cylinder, so it is never a substitute for the keyed Corbin Russwin CL3155, but it is what goes on the inactive leaf. The BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim cylindrical lever, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever in the 5400 Series. Both match the CL3155 on Grade 1 heavy duty classification.
    19) Could a keypad lever replace the CL3155 so we stop issuing keys?
    It changes how the door is controlled rather than substituting the function. The Lockey 2835 and 2835DC are mechanical pushbutton keyless lever locks with passage function for doors 1-3/16 inch to 2 inch thick, and the Lockey 1150 is a heavy duty mechanical keypad lever set with passage function for 1-1/8 inch to 2 inch doors. All are passage function, so the outside lever is not key-locked the way the Corbin Russwin CL3155 outside lever is locked and unlocked by key from outside.
