Corbin Russwin CL3172-KEYED Apartment Exit/Public Toilet Grade 1 Cylindrical Lever Lock with Vandal-Resistant T-Zone Construction

Commercial-Grade Keyed Cylindrical Lever Lock for Apartment Exit and Public Toilet Applications

The Corbin Russwin CL3172-KEYED is a patented Grade 1 cylindrical lever lock engineered for Apartment Exit/Public Toilet applications (ANSI function F88) in demanding commercial environments. Designed for door thicknesses of 1-3/4" to 2" with a 2-3/4" backset, this keyed lockset features a deadlocking latchbolt operable by lever from either side, except when the key inside locks the outside lever—placing the outside lever in a freewheeling position. The key outside retracts the latchbolt, the key inside unlocks the outside lever, and the inside lever remains always free. Built on the CL3100 Series platform, this lock is manufactured from steel with zinc dichromate treatment for corrosion resistance and incorporates Corbin Russwin’s proprietary T-Zone construction, which has been tested to over 15 million cycles—exceeding ANSI/BHMA Grade 1 standards by 15 times.

Corbin Russwin CL3172 NZD 626 – Frequently Asked Questions

1) How does the Corbin Russwin CL3172 apartment exit function actually work at the door?
The CL3172 is ANSI function F88. The deadlocking latchbolt retracts by lever from either side, until the key on the inside locks the outside lever, which then freewheels instead of turning. From that point the outside key retracts the latchbolt, the inside key unlocks the outside lever again, and the inside lever is always free so a tenant or restroom occupant can get out without a key. That freewheeling behavior is why it holds up on apartment entries and public toilet doors where people pull on a locked lever.
2) Will the CL3172 lever lock fit a 1-3/4 inch commercial door?
Yes. The CL3172 covers 1-3/4 inch through 2 inch doors, with a 2-3/4 inch backset. It will not work on a 1-3/8 inch door, so for thinner older interior leaves you need a different lock. It is also non-handed, so one lock works on a left or right hand opening with no reversing.
3) Can I drop this into the 161 prep that's already in my doors?
Yes, in most cases. The CL3100 Series retrofits most standard 161 cylindrical lock door preps and is non-handed, so a lock coming off an existing 2-3/4 inch backset bored opening swaps in without redrilling the door. Check the frame side too: it ships with an ANSI curved lip strike, 4-7/8 x 1-1/4 x 1-1/4 inches lip to center, which suits an ANSI-prepped frame rather than a small T-strike cutout.
4) Can I get the CL3172 keyed into the key system we already run in the building?
Yes. Standard supply is a conventional 6-pin cylinder in the L4 keyway with two nickel silver keys, and the CL3100 platform integrates into most existing facility key systems, accepts Schlage LFIC, and supports Access 3 and Pyramid security key systems. If your locksmith is keying on site, order it less cylinder (LC) or less core as CL6 for 6-pin LFIC or CL7 for 7-pin LFIC. Keying is specified on the order as KD keyed different, KA keyed alike across multiple locks, or none when you are supplying cores, and you can pass an existing key code.
5) Is the CL3172 fire rated for a labeled apartment entry door?
The CL3172 is fire rated, and the latch is a deadlatch with a square corner front measuring 2-1/4 x 1-1/8 inches on a 2-3/4 inch backset, which is the deadlocking latch a labeled opening needs to stay positively latched. It is a commercial-duty lockset built on ANSI/BHMA A156.2 Series 4000 Grade 1 performance.
6) What do I have to pick when ordering the CL3172 besides the finish?
Four choices decide the part. Lever design: AZ Armstrong, NZ Newport, or PZ Princeton. Rose: D rose 3-1/2 inch diameter is standard, with C rose 2-3/4 inch diameter, K rose 2-3/4 inch diameter, and E rose 3-1/8 inch square as alternatives. Cylinder: conventional 6-pin L4 keyway standard, or CL6, CL7, or LC less cylinder. Then keying, KD or KA. The most commonly specified build is the NZD Newport lever in 626 satin chrome.
7) What Grade 1 cylindrical lever lock works for a storeroom door instead of an apartment exit or public toilet door?
The Corbin Russwin CL3172 is built for the ANSI F88 apartment exit/public toilet function, where the key inside locks the outside lever and the inside lever is always free. If the opening needs to stay locked outside at all times with key entry, that is a storeroom function, and the Hager 2580 is a Grade 2 storeroom cylindrical lever lock for doors 1-3/8 inch to 2 inch thick. The Cal-Royal AG05 is another Grade 2 storeroom leverset with a deadlocking latchbolt, for doors 1-3/8 inch to 1-3/4 inch.
8) For a public restroom, is a privacy lever an alternative to the CL3172?
They handle the door differently. The CL3172 is a keyed lock on the apartment exit/public toilet function: a key inside locks the outside lever into a freewheeling position, and the outside key retracts the latchbolt, so staff keep key control. A privacy set is thumbturn operated with no key entry from the outside. If that is what the restroom calls for, the Hager 2540 is a Grade 2 privacy cylindrical lock with a Withnell lever for doors 1-3/8 inch to 2 inch, and the Arrow MK02-TA is a non-keyed privacy cylindrical lock with a Tudor knob, fire rated, for doors 1-3/4 inch to 2 inch.
9) Which alternatives to the CL3172 use a 2-3/4 inch backset?
The CL3172 is prepped for a 2-3/4 inch backset and is non-handed, with a square corner front deadlatch 2-1/4 inch by 1-1/8 inch. Among other keyed cylindrical levers, the Cal-Royal AG03 classroom lever also uses a 2-3/4 inch backset with a 6-pin Schlage C keyway keyed different. Note the Cal-Royal AG00 entrance lever is a 2-3/8 inch backset, so it will not drop into a 2-3/4 inch prep without the correct latch.
10) Is a Grade 1 cylindrical lever lock worth it over a Grade 2 on apartment corridor doors?
On a high-traffic multifamily corridor or a public restroom, yes. The CL3172 is Grade 1 with T-Zone construction, where the lockbody and latch interlock into a torque-resistant T in the twist area, tested past 15 million cycles. That is the part that survives people hanging on the lever. Grade 2 lever locks like the Hager 2525 entry or the Falcon B511CP6D entry/office are fine on lower-traffic interior openings, but they are a medium-duty answer to a heavy-duty door.
11) I need these locks to match the finishes already on my other doors. What finishes does the CL3172 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. 626 satin chrome is the usual commercial standard. If a smaller rose matches your existing trim better, the C or K rose at 2-3/4 inch diameter covers less of the door face than the standard 3-1/2 inch D rose.
12) If I later need a different function on the same door, do I have to buy a whole new lock?
Usually not. The CL3100 platform offers 18 functions including hospital privacy, and most function changes take only two parts, with the cylinder pulling out simply for change-outs. So a bank of apartment exit locks can be converted later without swapping trim or redoing the door prep.
13) Does the CL3172 come with the strike and latch, or do I order those separately?
Everything for the opening ships with it: a conventional 6-pin L4 keyway cylinder, the ANSI curved lip strike at 4-7/8 x 1-1/4 x 1-1/4 inches lip to center, the deadlatch with square corner front at 2-1/4 x 1-1/8 inches on a 2-3/4 inch backset, and two nickel silver keys. Nothing else is needed to hang it on a correctly prepped door.
14) Is there a non-keyed lever lock that matches the CL3172 for doors that do not need a cylinder?
The CL3172 is a keyed lock with a double cylinder keyed function and ships with a conventional 6-pin L4 keyway cylinder. For an opening that only needs the door to latch with free operation both sides, the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, for doors 1-3/8 inch to 2-1/4 inch. The Falcon T101 and the Design Hardware X75 are also Grade 1 passage leversets. In lighter Grade 2 duty, the Arrow GL01 passage lock covers doors 1-3/4 inch to 2 inch.
15) Is a keyless pushbutton lever lock an option in place of the CL3172 for a restroom or common area door?
It changes how access is controlled. The CL3172 uses a conventional 6-pin L4 keyway cylinder and integrates into a facility key system, with less-core LFIC 6-pin and 7-pin options also offered. If code-based access is preferred over keys, 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 Lockey 1150 is a heavy duty mechanical keypad lever set for doors 1-1/8 inch to 2 inch.
16) What is a lighter-duty entry lever alternative to the CL3172 for a low-traffic tenant door?
The CL3172 is a Grade 1 commercial cylindrical lever lock in steel with a zinc dichromated finish for corrosion resistance. Where the traffic is lighter and an entry or office function suits, the Hager 2525 is a Grade 2 commercial cylindrical entry lever lock for doors 1-3/8 inch to 2 inch, and the Falcon B511CP6D is a Grade 2 medium duty cylindrical lever with entry/office function. The Cal-Royal AUS00 is a Grade 3 entrance/office lever for doors 1-3/8 inch to 1-3/4 inch.
17) Will a residential-grade lever set substitute for the CL3172 in an apartment building?
The CL3172 is specified as commercial and is Grade 1 on a 1-3/4 inch to 2 inch door, and it is fire rated. Residential-grade levers such as the Kwikset 200BRNL Breton passage and the Kwikset 300BRNL Breton privacy are Grade 3 and built for doors 1-3/8 inch to 1-3/4 inch, and the Master Lock BC Series keyed entry lever is also Grade 3. Those cover unit interior doors, not a rated corridor or restroom opening on a 2 inch door.
18) Is there an antimicrobial option for healthcare and public restroom doors?
The CL3100 Series is offered with Microshield antimicrobial coating, which is the version specified for healthcare, institutional, and high-contact public washroom doors. The lock body itself is steel, zinc dichromated for corrosion resistance, which matters in the humid environments restroom hardware lives in.
19) Does the CL3172 contribute to LEED on a renovation?
The lock is made from 68 percent post-consumer recycled content under LEED MR credit 4, which is the number a sustainability-minded spec or a green distributor will ask for.
20) Can a dummy lever be used with the CL3172 on an inactive leaf?
A dummy trim is not a substitute for the CL3172, which is a keyed Grade 1 cylindrical lock with a latchbolt; a dummy has no latch and is pull-only trim for inactive leaves. For that use the BEST 9K Series 1DT single dummy trim, a Grade 1 non-keyed heavy duty cylindrical lever trim, or the Accentra 455LN Augusta Grade 1 single dummy. The BEST 7KC single dummy trim is the Grade 2 medium duty equivalent.
