Corbin Russwin CL3175-KEYED Corridor/Dormitory Grade 1 Cylindrical Lever Lock with Vandal Resistance and T-Zone Construction

Patented Grade 1 Cylindrical Lever Lock Engineered for High-Traffic Commercial Applications

The Corbin Russwin CL3175-KEYED is a patented Grade 1 cylindrical lever lock from the CL3100 Series, designed for Corridor/Dormitory (ANSI function F90) applications in demanding commercial, institutional, and industrial environments. This keyed cylindrical lever lock accommodates door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, and features a conventional 6-pin cylinder with two nickel silver keys included.

Corbin Russwin CL3175 NZD 626 – Frequently Asked Questions

1) How does the Corbin Russwin CL3175 corridor/dormitory function actually work on a dorm room door?
The CL3175 is ANSI F90 corridor/dormitory. The lever retracts the latchbolt from either side unless the pushbutton on the inside or the key locks the outside lever. Once the pushbutton is set, the outside lever stays rigid and needs the key; turning the inside lever or simply closing the door releases the button. The inside lever is always free, so nobody gets locked in. That is the behavior you want on a dorm or apartment corridor door where the occupant controls whether the outside lever works.
2) Will the CL3175 fit a 1-3/4 inch commercial door with a 161 prep?
Yes. The CL3175 covers door thicknesses of 1-3/4 inch through 2 inch and uses a 2-3/4 inch backset, and it retrofits most standard 161 cylindrical prep. It is non-handed, so there is no hand to specify and the same lock works on either swing. If your doors are thinner than 1-3/4 inch, this is the wrong lock for them.
3) Will the CL3175 latch into the strike already in my frame?
It ships with an ANSI curved lip strike, 4-7/8 x 1-1/4 x 1-1/4 inch lip to center, and a square corner deadlatch front measuring 2-1/4 x 1-1/8 inches on a 2-3/4 inch backset. If your frames are already prepped for ANSI strikes (standard on hollow metal commercial frames), the supplied strike drops straight in. Frames cut for a small T-strike or a round corner face will need the opening enlarged or the existing strike reused.
4) Can I get the CL3175 keyed into my existing master key system?
The standard build is a conventional 6-pin cylinder in the L4 keyway with two nickel silver keys, and it integrates into most existing key systems. If you key your building on Schlage, the lock accepts Schlage LFIC, and it also works with Access 3 and Pyramid security key systems. For a house system you already pin yourself, order it LC (less conventional cylinder) or CL6/CL7 for less-core Corbin Russwin 6-pin or 7-pin LFIC and drop in your own core. Keying is specified as keyed different or keyed alike at order time.
5) Can the Corbin Russwin CL3175 go on a fire rated door?
Yes, the CL3175 is fire rated and its deadlatch is the right latch type for a rated opening. It is a Grade 1 commercial lock, so it also meets the duty level normally specified on rated corridor and stair doors.
6) What is a Grade 1 storeroom lever I can use instead of the CL3175 on doors that should stay locked at all times?
The Corbin Russwin CL3175 is a Corridor/Dormitory (ANSI F90) lock, so the outside lever is only locked when someone presses the pushbutton or turns the key. If you need an opening that stays secured without relying on a pushbutton, the Hager 2580 is a storeroom-function cylindrical lever lock for doors 1-3/8 inch to 2 inch thick, and the Cal-Royal AG05 is a storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. Both are Grade 2 rather than the CL3175's Grade 1, so match the grade to the traffic level on the opening.
7) Which classroom-function lever should I order for a school if the corridor lock is the Corbin Russwin CL3175?
The CL3175 is a Corridor/Dormitory function and is not a classroom lock - the inside lever releases the pushbutton, which is not what a classroom lockdown sequence calls for. For classroom openings, the Dexter C1000 is a Grade 1 classroom cylindrical lever lock with clutching for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 classroom security version adds key control from the inside, also Grade 1 for 1-3/8 inch to 1-3/4 inch doors. The Cal-Royal AG03 is a Grade 2 classroom lever with a 6-pin Schlage C keyway and a 2-3/4 inch backset, which matches the CL3175's 2-3/4 inch backset prep.
8) For a patient room or utility door, what should I specify instead of the Corbin Russwin CL3175?
The CL3175's Corridor/Dormitory function lets the inside lever release the pushbutton, which is not appropriate where the room side should not control the lock. For those openings, the Dexter C1000 Asylum is a Grade 1 F87 asylum function cylindrical lock for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy duty asylum/institution/utility cylindrical lock with a conventional Schlage C keyway cylinder. Asylum function is keyed both sides, so plan the keying accordingly.
9) What do I have to specify when ordering a CL3175 lever lock?
Four choices plus keying. Lever design: AZ Armstrong, NZ Newport, or PZ Princeton. Rose: C rose 2-3/4 inch diameter, D rose 3-1/2 inch diameter (standard), E rose 3-1/8 inch square, or K rose 2-3/4 inch diameter. Finish: 605, 606, 611, 612, 613, 618, 619, 625, 626, 722, BSP black suede, or WSP white suede powder coat. Cylinder: conventional 6-pin L4 standard, CL6 or CL7 less core, or LC less cylinder. Then keyed different or keyed alike, with a key code field if you are matching an existing system. 626 satin chrome with the NZ Newport lever is the most common combination.
10) Is a corridor/dormitory lock the right function, or do I need a classroom or storeroom lock?
Pick by who controls the lock. Corridor/dormitory (the CL3175) lets the occupant lock the outside lever with a pushbutton from inside, and it auto-releases when the door closes, which suits dorm rooms, apartments, and offices where the resident locks up. If you want the door always locked from outside and free from inside with no button, that is a storeroom function like the Hager 2580 with Withnell lever or the Cal-Royal AG05. If staff must lock and unlock the outside lever by key only, choose a classroom function such as the Cal-Royal AG03 or the Dexter C1000 classroom lever.
11) Is the CL3175 heavy enough for a high traffic building entrance corridor?
It is built for it. The lock is Grade 1 commercial with patented T-Zone construction that interlocks the aligning and latch tubes into a torque resistant T in the twist area, the part of a lever lock that fails first when people hang on it. Corbin Russwin tests it past 15 million cycles. The body is steel with a zinc dichromate treatment for corrosion resistance. For healthcare or school corridors there is also a Microshield antimicrobial coating option.
12) What are the Grade 1 alternatives to the Corbin Russwin CL3175 if I need a different function on the same doors?
Staying at Grade 1 cylindrical, the Falcon K101 covers passage in the K Series and is fire rated across 1-3/8 to 2-1/4 inch doors, the Falcon T101 is a heavy duty Grade 1 passage lever, and the Dexter C1000 Series runs Grade 1 in asylum, classroom, classroom security, and passage functions. For matching trim on doors that need no latch at all, the BEST 9K Series 1DT single dummy is Grade 1. None of these is a corridor/dormitory function, so if you need the pushbutton behavior the CL3175 is the one to keep.
13) I need the matching non-keyed passage lever to go with Corbin Russwin CL3175 corridor locks on the same floor. What are my options?
The CL3175 is keyed with a conventional 6-pin L4 keyway cylinder, so for closets and non-secured openings you want a passage lock instead. Grade 1 passage cylindrical levers include the Falcon K101, rated for 1-3/8 inch to 2-1/4 inch doors with a fire rating and non-handed levers, the Falcon T101 heavy duty passage lever with pressure release technology, the Dexter C1000 passage with clutching for 1-3/8 inch to 1-3/4 inch doors, and the Design Hardware X75 flat-lever passage set for 1-3/4 inch doors. All four share the CL3175's Grade 1 rating.
14) Is there a lower-cost Grade 2 alternative to the Corbin Russwin CL3175 for a light-traffic office door?
The CL3175 is a Grade 1 lever built for commercial high-traffic use. Where the opening does not need Grade 1, the Falcon B511CP6D is a Grade 2 medium duty cylindrical lever with entry/office function, the Hager 2525 is a Grade 2 commercial cylindrical entry lock for 1-3/8 inch to 2 inch doors, and the Cal-Royal AG00 entrance lever uses a 6-pin Schlage C keyway on a 2-3/8 inch backset. Note the AG00's 2-3/8 inch backset differs from the CL3175's 2-3/4 inch backset, so confirm the existing bore before swapping.
15) Can I use a Baldwin or Emtek lever in place of a Corbin Russwin CL3175?
No - those serve different openings. The CL3175 is a keyed Grade 1 commercial cylindrical lever with Corridor/Dormitory function. The Baldwin Estate 5103 is offered in passage, privacy, and handed half-dummy configurations, and the Emtek Arts and Crafts and Cortina leversets in the same family are dummy pairs with no latch at all. Dummy trim mounts as a pull only, so it cannot replace a keyed corridor lock. Use Baldwin or Emtek where you want decorative trim on a non-latching or non-keyed opening.
16) Is there a keyless alternative to the Corbin Russwin CL3175 for a door where I do not want to issue keys?
The CL3175 is a keyed lock with a conventional 6-pin L4 keyway and can also be ordered less cylinder or as a less-core LFIC prep. If you would rather run a code, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for 1-3/16 inch to 2 inch doors, the Lockey 2835DC adds a double combination, and the Lockey 1150 is a heavy duty mechanical keypad lever set for 1-1/8 inch to 2 inch doors. The Delaney LP250 is a Grade 2 electronic keypad leverlock. Keep in mind these are code-driven rather than the CL3175's corridor pushbutton-and-key sequence.
17) Is a Kwikset or Callan lever an acceptable substitute for the Corbin Russwin CL3175 in an apartment corridor?
They are built to a different duty level. The CL3175 is a Grade 1 commercial lever. The Kwikset 200BRNL Breton passage and 300BRNL Breton privacy sets are Grade 3 for 1-3/8 inch to 1-3/4 inch doors, and the Callan Artino and Bennett entrance leversets are also Grade 3. Grade 3 suits residential unit interiors; for shared corridor and stair doors that see the whole building's traffic, stay with the Grade 1 CL3175.
18) Can I match the CL3175 finish to the other hardware already in my building?
Twelve finishes are offered: 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. 626 satin chrome is the common commercial standard and the one most buildings already run.
19) Does the CL3175 count toward LEED on a renovation?
The lock is made from 68 percent post-consumer recycled content, credited under LEED MR credit 4. That is the figure to hand your submittal reviewer if recycled content is being tracked on the project.
20) What do I order to get dummy trim that matches Corbin Russwin CL3175 locks in the same corridor?
The CL3175 itself is a keyed working lock, so a separate dummy is needed for inactive leaves. Grade 1 single dummy cylindrical lever trim includes the BEST 9K Series 1DT, a heavy duty non-keyed single dummy, and the Accentra 455LN Augusta from the 5400 Series, also Grade 1. If the inactive door does not need Grade 1, the BEST 7KC Series 1DT is a Grade 2 medium duty single dummy trim.
21) What is the difference between the Corbin Russwin CL3175 and a knob-style lock like the Arrow HK11 or MK02?
The CL3175 is a lever-handle cylindrical lock, which is what ADA-driven specs generally call for on commercial openings. The Arrow HK11 is a turn-pushbutton entrance cylindrical lock with a ball knob for 1-3/8 inch to 1-3/4 inch doors, and the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob for 1-3/4 inch to 2 inch doors. Knob trim changes both the operation and the look at the door, so specify levers if the rest of the building is levered.
