Corbin Russwin CL3561 NZD Grade 1 Entry/Office Cylindrical Lever Lock, Newport Lever, SFIC Less Core

Heavy-Duty Commercial Cylindrical Lockset for Entrance and Office Applications

The Corbin Russwin CL3561 NZD Grade 1 Entry/Office Cylindrical Lever Lock is a heavy-duty, ANSI/BHMA Grade 1 certified keyed cylindrical lever lock engineered for demanding commercial, institutional, and multi-family environments. Featuring the Newport (NZD) lever in a 626 Satin Chrome finish, this lockset accommodates door thicknesses from 1-3/8" to 1-3/4" with a 2-3/4" backset, and is supplied SFIC (Small Format Interchangeable Core) Less Core for flexible keying system integration. Part of the CL3500 Series, it complements the CL3300 Series Extra Heavy-Duty Grade 1 and CL3800 Series Standard-Duty Grade 2 locksets, allowing consistent aesthetics and reduced project costs across an entire facility.

Professional Features & Benefits

Door Thickness Compatibility: Designed for doors ranging from 1-3/8" to 1-3/4" thick with a 2-3/4" backset, ensuring broad compatibility with standard commercial door preparations.
ANSI Function F82A (Entrance/Office): Deadlocking latchbolt operated by lever from either side, except when push button locks the outside lever. Push button is released by turning the inside lever or by key in the outside lever; closing the door does not release the push button, and the inside lever remains always free.
ANSI/BHMA Grade 1 Certification: Meets the highest commercial duty rating for cylindrical locksets, providing fire-rated performance and long-term reliability in high-traffic applications.
Solid Cast Newport Lever & Non-Handed Design: Solid cast levers with independent return springs prevent lever sag, and the non-handed configuration simplifies installation on any door without special ordering.
Through-Bolted Cylindrical Chassis: Prevents rotation and ensures proper alignment throughout the life of the lock, maintaining consistent operation in heavy-use environments.
Standard Cylinder & Strike Included: Supplied with a brass, 6-pin, L4 keyway cylinder (0-bitted standard), two nickel silver keys, and an ANSI curved lip strike measuring 4-7/8" x 1-1/4" with 1-1/4" lip to center.
SFIC Less Core Configuration: Prepared for Small Format Interchangeable Core systems, allowing facility managers to integrate with existing master key or access control programs without replacing the entire lockset.
Trim & Keying Compatibility: Trim and keying are compatible with other Corbin Russwin locksets, reducing overall project cost when combining cylindrical lockset series throughout a facility.
Corrosion-Resistant Construction: Chassis constructed of steel with zinc dichromate treatment for corrosion resistance, supporting long service life in commercial environments.

Corbin Russwin CL3561 NZD 626 M08 – Frequently Asked Questions

1) What does the Entrance/Office push button function on the CL3561 actually do day to day?

It is the F82A entry/office setup. The latchbolt is deadlocking and the lever retracts it from either side until you press the push button in the inside rose, which locks the outside lever. The inside lever is always free, so egress is never blocked. Pulling the door shut does NOT release the button, so the office stays locked after everyone leaves. To unlock, turn the inside lever or use the key in the outside lever.

2) The CL3561 is listed as SFIC less core. Do I need to buy a core separately?

Yes. The NZD variant ships prepped for a Small Format Interchangeable Core and no core is included, so you supply the SFIC core keyed into your existing master system. That is the point of the configuration: a property or facility already running SFIC can drop its own cores in without changing locksets.

3) Will the CL3561 latch into the strike already in my hollow metal frame?

It comes with an ANSI curved lip strike, 4-7/8 x 1-1/4 inches with 1-1/4 inch lip to center, which is the standard ANSI frame cutout. If your frame has a different jamb depth or wood trim, other lip lengths are selectable: 1 inch, 1-1/8, 1-1/4 (standard), 1-3/8, and 1-1/2. Match the lip so it just covers the jamb edge without proud metal in the traffic path.

4) Is the CL3561 approved for a fire rated office door?

Fire rated, yes, and ANSI/BHMA Grade 1 certified. The deadlocking latchbolt with an always-free inside lever suits a rated opening where egress cannot be locked. The steel chassis is zinc dichromated for corrosion resistance.

5) My door is 2 inches thick. Which Grade 1 lever covers that instead of the CL3561?

The Corbin Russwin CL3561 is built for doors 1-3/8 inch to 1-3/4 inch thick. For a thicker leaf, the Falcon K101 is a Grade 1 heavy duty fire rated cylindrical lock rated for 1-3/8 inch to 2-1/4 inch doors, and the Dexter C1000 asylum function covers 1-3/8 inch to 2 inch. Note the K101 is passage function, so it is not a keyed substitute.

6) What is the closest same-function alternative to the Corbin Russwin CL3561 if a Grade 2 lever is acceptable?

The Falcon B511CP6D is a Grade 2 medium duty cylindrical lever lock with the same Entrance/Office function as the CL3561, which is Grade 1 heavy duty. Both give you a keyed outside lever for an office door; the difference is the duty rating and certification level behind it.

7) Can I use a classroom or storeroom lock in place of the CL3561 Entry/Office lock?

They are different functions and not interchangeable. The CL3561 uses a push button on the inside to lock the outside lever, with the inside lever always free. The Dexter C1000 classroom lever is a Grade 1 keyed classroom function, and the Cal-Royal AG05 is a Grade 2 storeroom lockset with a deadlocking latchbolt where the outside lever stays locked at all times. Choose by how the occupant is meant to secure the door, not by grade alone.

8) My openings are prepped for a 2-3/8 inch backset. Does the CL3561 fit?

No, the CL3561 ships with a 2-3/4 inch backset deadlatch. For a 2-3/8 inch prep, the Cal-Royal AG00 entrance lever is a Grade 2 lock with a 6-pin Schlage C keyway and a 2-3/8 inch backset for doors 1-3/8 inch to 1-3/4 inch thick.

9) Do I have to order the CL3561 handed for a left or right swing door?

No handing to specify. The CL3561 is non-handed, with solid cast Newport levers on independent return springs, so one part number covers either swing and the lever can be set for the door you are on. That is one less line item to get wrong on a multi-door order.

10) What latch comes with the CL3561, and can I get a rounded corner front for a wood door?

Standard is the 586F17 deadlatch, square corner front, 2-1/4 x 1-1/8 inches, 2-3/4 inch backset. If the existing mortise in a wood door was routed with a radius, choose the 596F67 rounded corner deadlatch instead at the same size and backset. Picking the front that matches the old pocket saves you re-chiseling the edge.

11) I need twenty of these to all work on one key. Can the CL3561 be keyed alike?

Yes. Keying is selectable as KD keyed different (standard) or KA keyed alike for a group of locks on one key, and there is a field for special cylinder or keying requirements if you are tying into an existing master system. Note the NZD build is SFIC less core, so the keying decision follows the cores you supply.

12) How do I keep the CL3561 matching the other Corbin Russwin locks already in the building?

Trim and keying on the CL3500 Series are compatible with other Corbin Russwin locksets, so the Newport lever in 626 satin chrome can sit alongside the CL3300 Series extra heavy duty Grade 1 and the CL3800 Series standard duty Grade 2 with a consistent look. That lets you spec heavier locks on entries and lighter ones on interior doors without mismatched hardware.

13) What else could I use instead of the CL3561 for an entry/office door if I don't need Grade 1?

For the same entrance/office function at a lighter duty, the Falcon B511CP6D is a Grade 2 medium duty cylindrical lever lock, and the Cal-Royal AUS00 is a Grade 3 entrance/office lever that also covers 1-3/8 to 1-3/4 inch doors. Step down only where traffic is light; for high-traffic commercial and institutional openings the Grade 1 heavy duty CL3561 is the one that matches the spec.

14) Is a dummy or passage lever a substitute for the CL3561 on an office door?

No. Those are not keyed. The CL3561 is a single cylinder keyed lock with a deadlocking latchbolt and push button locking. A BEST 9K 1DT single dummy trim is a pull only with no latch, and the Dexter C1000 passage version latches but never locks. Use those on closets and inactive leaves, not on a door that has to secure an office.

15) I need the same office lever function but on a lighter-duty budget door. What else carries Entrance/Office?

The Cal-Royal AUS00 is a Grade 3 Entrance/Office lever lock with a solid brass forged body, fitting doors 1-3/8 inch to 1-3/4 inch thick, the same door thickness range the Corbin Russwin CL3561 covers. The CL3561 is Grade 1 heavy duty; the AUS00 sits two grades below it for lighter traffic openings.

16) The opening does not need to lock. What is the non-keyed equivalent to the CL3561?

The CL3561 is a keyed single cylinder lever. If the door only needs latching, the Dexter C1000 passage lever is Grade 1 and non-keyed for 1-3/8 inch to 1-3/4 inch doors, and the Design Hardware X75 is a Grade 1 passage lever lockset for 1-3/4 inch doors. Both drop the cylinder entirely, so there is no push button lockout.

17) Is a keypad leverset a substitute for the CL3561 SFIC lock?

No. The CL3561 is prepared for a small format interchangeable core so it ties into an existing master key program. Keyless options such as the Lockey 2835 mechanical pushbutton lever, which fits doors 1 3/16 inch to 2 inch, or the Delaney LP250 Grade 2 electronic keypad leverlock work on codes rather than keys and will not join a Corbin Russwin keying system.

18) If I skip the SFIC option, what cylinder does the CL3561 normally ship with?

The CL3500 Series standard cylinder is a brass 6-pin, L4 keyway conventional cylinder supplied 0-bitted with two nickel silver keys. The NZD build here is instead prepped less core for Small Format Interchangeable Core, so you are choosing between running the Corbin Russwin L4 conventional keyway or dropping your own SFIC cores in.

19) Will the CL3561 chassis loosen and spin on a high-traffic apartment door?

The chassis is through-bolted, which stops rotation and holds alignment over the life of the lock, and the levers are solid cast with independent return springs so they resist sag from people hanging on them. Construction is steel with a zinc dichromate treatment for corrosion resistance. It is rated heavy duty Grade 1 for exactly this kind of traffic.

20) I need matching non-locking trim on adjacent doors to go with CL3561 locks. What dummy levers are available?

The CL3561 itself is a keyed lever. For adjacent inactive leaves, the BEST 9K Series 1DT is a Grade 1 heavy duty non-keyed single dummy trim lever, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever. Both match the Grade 1 duty level of the CL3561 without any latching mechanism.

21) I want a knob instead of a lever for an entrance door. What is comparable to the CL3561?

The CL3561 is a non-handed lever trim lock. For a knob, the Arrow HK11-BB is a turn-pushbutton entrance cylindrical lock with a ball knob and conventional cylinder for doors 1-3/8 inch to 1-3/4 inch, the same door range. Note that knob trim generally will not satisfy ADA lever requirements where those apply.
