Corbin Russwin CL3157-KEYED Grade 1 Storeroom/Closet Cylindrical Lever Lock with Vandal Resistance and T-Zone Construction

Commercial-Grade Keyed Cylindrical Lever Lock for High-Traffic Storeroom and Closet Applications

The Corbin Russwin CL3157-KEYED is a patented Grade 1 cylindrical lever lock engineered for storeroom and closet applications (ANSI function F86) in demanding commercial, industrial, and institutional environments. Featuring the proprietary T-Zone construction that interlocks the aligning and latch tubes to form a torque-resistant "T" in the critical twist area, this lock is tested to over 15 million cycles — exceeding ANSI/BHMA A156.2 Series 4000 Grade 1 standards by 15 times. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, the CL3157-KEYED delivers a deadlocking latchbolt operated by key in the outside lever or by rotating the inside lever, with the inside lever always free for safe egress. The lock body is constructed from steel with zinc dichromate treatment for corrosion resistance, and the non-handed design retrofits most standard 161 cylindrical lock door preparations.

Professional Features & Benefits

  • Vandal-Resistant T-Zone Construction: Unique interlocking design between the lockbody and latch provides strength and durability far exceeding Grade 1 standards, resisting forced entry and vandalism in high-use environments.

  • Corrosion-Resistant Construction: Lock body manufactured from steel with zinc dichromate treatment, ensuring long-lasting performance in demanding commercial environments.
  • Flexible Configuration Options: 18 functions available (most requiring only 2 parts to change function); non-handed design retrofits most standard 161 cylindrical lock door preps; integrates into most existing key systems and accepts Schlage® LFIC.

Corbin Russwin CL3157 NZD 626 – Frequently Asked Questions

1) Will the Corbin Russwin CL3157 fit a 1-3/8 inch door?
No. The CL3157 cylindrical lever lock is built for doors 1-3/4 inches to 2 inches thick, which covers standard commercial doors but not the thinner 1-3/8 inch interior doors common in older residential construction. For a 1-3/8 inch opening you need a different lock; the Dexter C1000 Series covers 1-3/8 to 1-3/4 inches, and the Falcon K101 covers 1-3/8 to 2-1/4 inches.
2) Can I drop the CL3157 into an existing 161 cylindrical lock prep?
Yes. The CL3157 is non-handed and retrofits most standard 161 cylindrical door preps, with a 2-3/4 inch backset. If the door you are replacing was drilled for a 2-3/8 inch backset, the crossbore centerline sits in the wrong place and the lock will not line up.
3) Do I need to specify handing when ordering a CL3157 storeroom lever?
No handing to specify. The CL3157 is a non-handed lock, so one part number works on a left or right hand door. You do specify lever design (Armstrong, Newport, or Princeton), rose (C 2-3/4 inch round, D 3-1/2 inch round, E 3-1/8 inch square, or K 2-3/4 inch round), finish, and cylinder option.
4) How does the storeroom function on the CL3157 actually behave day to day?
The outside lever is always locked and freewheels when you turn it, so nobody gets in without a key. A key in the outside lever retracts the deadlocking latchbolt. The inside lever is always free, so anyone in the room can walk out without a key or a thumbturn. That is ANSI function F86, and it is why this is the standard choice for stock rooms, electrical closets, and back-of-house storage.
5) Can I get the CL3157 keyed into my building's existing key system?
Yes. Ordering options include the standard conventional 6-pin cylinder in the L4 keyway, CL6 less core for a Corbin Russwin 6-pin or 7-pin large format interchangeable core, or LC less conventional cylinder if you are supplying your own. The lock also accepts Schlage LFIC. On the order you pick keyed different, keyed alike for multiple doors, or no cylinder at all.
6) Will the CL3157 latch work with the strike already in my frame?
The lock ships with a deadlatch having a square corner front, 2-1/4 by 1-1/8 inches, on a 2-3/4 inch backset, plus an ANSI curved lip strike 4-7/8 by 1-1/4 inches with 1-1/4 inch lip to center. If your frame has the standard ANSI strike cutout, the supplied strike drops straight in. A frame prepped for a smaller T-strike will need to be modified or the existing strike reused only if the lip length matches your jamb-to-stop dimension.
7) I need a Grade 1 lever lock but the door is 1-3/8 inch thick. What can I use instead of the CL3157?
The CL3157 is built for 1-3/4 inch to 2 inch doors. For thinner doors at the same Grade 1 level, the Falcon K101 passage lever covers 1-3/8 inch to 2-1/4 inch and is fire rated, and the Dexter C1000 asylum lock covers 1-3/8 inch to 2 inch. Note the function difference: the K101 is a passage lock with no key, and the C1000 asylum lock is an F87 asylum function, while the CL3157 is a keyed storeroom lock whose outside lever is always locked and retracts only by key.
8) For a classroom door rather than a storeroom, what should I order instead of the CL3157?
The CL3157 is a storeroom/closet function, where the outside lever is always locked. For a classroom you want a classroom function: the Dexter C1000 classroom lever is Grade 1 with a clutching keyed lever for 1-3/8 inch to 1-3/4 inch doors, and the Dexter C1000 classroom security version is Grade 1 as well. In Grade 2, the Cal-Royal AG03 classroom lever uses a 6-pin Schlage C keyway keyed different with a 2-3/4 inch backset, matching the CL3157 backset.
9) Is the CL3157 approved for a fire rated storeroom door?
The CL3157 carries a fire rating, and it is a Grade 1 lock under ANSI/BHMA A156.2 Series 4000. Being a storeroom function with an always-free inside lever, it also keeps the egress side latch-retracting without a key.
10) Is a Grade 1 lever lock worth it over a Grade 2 storeroom lock for a school corridor closet?
For heavy abuse, yes. The CL3157 uses T-Zone construction that interlocks the aligning and latch tubes in the twist area, tested past 15 million cycles, which is 15 times the ANSI/BHMA A156.2 Series 4000 Grade 1 requirement. That matters where levers get hung on and pried. If the door is low traffic and budget drives the spec, Grade 2 storeroom options exist, such as the Hager 2580 with Withnell lever or the Cal-Royal AG05, both storeroom function.
11) Is a passage lever the same thing as the CL3157 storeroom lock?
No. The CL3157 is keyed, single cylinder, with a deadlocking latchbolt retracted by key in the outside lever. Passage levers such as the Falcon K101 and Dexter C1000 passage, both Grade 1, and the Grade 2 Falcon B101, Arrow GL01, Hager 2510 and Accentra 5301LN carry no cylinder at all and let both levers turn freely at any time. Use a passage lever only where the door never needs to be secured; use the CL3157 where the storeroom side must stay locked.
12) What should I use for an office or entry door where staff need to lock and unlock from inside, instead of a CL3157?
The CL3157 storeroom lock has no inside locking control; the outside lever stays locked and opens by key only. For an office door where the occupant sets the lock, look at entrance/office function locks: the Falcon B511CP6D is a Grade 2 cylindrical entry/office lever, the Hager 2525 is a Grade 2 commercial entry lever for 1-3/8 inch to 2 inch doors, and the Cal-Royal AG00 entrance lever uses a 6-pin Schlage C keyway with a 2-3/8 inch backset.
13) I want keyless access on a storeroom door. What replaces the CL3157 key cylinder?
The CL3157 ships with a conventional 6-pin L4 keyway cylinder. If you would rather issue a code than keys, the Lockey 2835 mechanical pushbutton keyless lever lock fits 1-3/16 inch to 2 inch doors and is ADA compliant, the Lockey 2835DC adds a double combination, and the Lockey 1150 heavy duty keypad lever set covers 1-1/8 inch to 2 inch. Electronic options include the Delaney LP250 Grade 2 keypad leverlock. Those Lockey units are passage function, so they release the latch on code rather than holding a storeroom lockdown by key.
14) I need a matching inactive lever for the second leaf of a pair where the active leaf has a CL3157. What do I order?
The CL3157 is a keyed, working storeroom lever, so it is not the part for an inactive leaf. Dummy trim with no latch includes the BEST 9K Series 1DT single dummy, which is Grade 1 heavy duty, the BEST 7KC Series 1DT in Grade 2 medium duty, and the Accentra 455LN Augusta single dummy in Grade 1. Dummy trim is surface applied and does not use the 2-3/4 inch backset bore the CL3157 requires.
15) For a utility or restroom door in an institution, is the CL3157 the right function or is there a better fit?
The CL3157 is storeroom/closet, so the outside lever never unlocks by thumbturn and the inside lever is always free for egress. For a restroom or patient-area door, look at privacy or asylum functions instead: the Hager 2540 with Withnell lever, the Arrow MK02-TA privacy knob for 1-3/4 inch to 2 inch fire rated doors, the Grade 1 Dexter C1000 asylum (F87), or the Arrow MK33-BD-CS asylum lock with a conventional Schlage C keyway cylinder.
16) Our building is keyed to Schlage. Does that rule out the Corbin Russwin CL3157?
Not necessarily. The CL3157 comes standard with a conventional 6-pin L4 keyway cylinder, and it can also be ordered LC less conventional cylinder or with CL6 less core for a 6-pin or 7-pin Corbin Russwin LFIC, so you can supply the cylinder your system uses. On the Yale/Accentra side, the Accentra 107S is a Schlage cylinder adapter kit for Yale hardware. Locks that ship natively on a Schlage C keyway include the Cal-Royal AG00 and AG03 and the Arrow MK33-BD-CS.
17) What finishes does the Corbin Russwin CL3157 come in, and can I match the rest of my building?
Twelve finishes: 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 with the Newport lever is the usual commercial pick, so it is the easiest to standardize a building on.
18) Is the CL3157 suitable for a hospital or clinic where surfaces get wiped constantly?
It suits that use. The lock body is steel with a zinc dichromate treatment for corrosion resistance, and the CL3100 Series is offered with Microshield antimicrobial coating for high-touch surfaces in healthcare and educational buildings. The lever is a lever, not a knob, which is what most institutional specs call for.
19) I need a matching passage or dummy lever for the adjacent doors. Can I change the CL3157 to another function?
The CL3100 Series offers 18 functions, and most function changes take only two parts, so a locksmith can convert rather than restock. Keeping the same lever and rose across the openings is what makes the corridor look consistent. If you would rather buy a separate non-keyed lever for the passage doors, Grade 1 options include the Falcon K101 passage and the BEST 9K Series 1DT single dummy trim.
20) Does the CL3157 count toward LEED recycled content credit?
It is made from 68% post-consumer recycled content under LEED MR credit 4, which is the figure a spec writer or sustainable distributor will want on record for the submittal.
