Corbin Russwin CL3510 NZD 626 – Frequently Asked Questions

1) What else could I use instead of the Corbin Russwin CL3510 for a commercial passage door?
Direct commercial alternatives we carry include the Accentra 5301LN Augusta and the Accentra 4601LN, both Grade 2 passage cylindricals, the Hager 2510 with the Withnell lever, and the Design Hardware X75 flat lever passage set. The Falcon K101 is the closest heavy duty match. On thickness, the Hager 2510 covers 1-3/8 to 2 inches and the Falcon K101 covers 1-3/8 to 2-1/4 inches, so if your door runs thicker than 1-3/4 inches those two reach further than the CL3510 does.
2) What does passage function mean on a CL3510 lever lock, and can it be locked?
Passage means no lock at all. On the CL3510 the latchbolt retracts by lever from either side and both levers are always free, so the door latches shut but never secures. It's non-keyed and takes no cylinder. Use it on corridors, closets and hall doors. If the opening needs to lock, this is the wrong function, pick an entry, storeroom or privacy lock instead.
3) Can I put a Corbin Russwin CL3510 on an aluminum storefront door?
Not usually. The CL3510 cylindrical lever needs a minimum stile of 4-1/2 inches, and narrow stile aluminum storefront doors are typically well under that. For a glass front opening you want narrow stile hardware or a rim exit device with lever trim. On a hollow metal or wood door with a 4-1/2 inch or wider stile, the CL3510 is fine.
4) What should I use on a door thicker than 1-3/4 inch if the CL3510 will not fit?
The CL3510 is specified for 1-3/8 inch to 1-3/4 inch doors. For a thicker leaf, the Falcon K101 is a Grade 1 heavy-duty passage lever lock rated for 1-3/8 inch to 2-1/4 inch. Staying at Grade 2, the Hager 2510 passage lever covers 1-3/8 inch to 2 inch, and the Arrow GL01 passage lever with the Sierra lever covers 1-3/4 inch to 2 inch.
5) The opening needs to lock, not just latch. What takes the place of the CL3510?
The CL3510 is non-keyed passage function: latchbolt by lever from either side, both levers always free. When the door has to secure, the Dexter C1000 Entry/Office is a Grade 1 keyed cylindrical lever lock for 1-3/8 inch to 1-3/4 inch doors, the Dexter C1000 Classroom is the Grade 1 keyed classroom function, and the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. For a bed or bath door needing only a privacy turn, the Hager 2540 uses the Withnell lever.
6) Which lever styles and finishes can I get on the Corbin Russwin CL3500 Series passage lock?
Three lever designs: AZD Armstrong, NZD Newport and PZD Princeton. Finishes run to fourteen, including 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil-rubbed satin bronze, 613E and 613L dark oxidized bronze, 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 a building already standardized on commercial hardware, 626 satin chrome is the volume finish and the easiest to match across other openings.
7) Is the CL3510 a heavy duty lock, or is there something tougher for a high traffic corridor?
The CL3510 is a heavy duty commercial cylindrical lever built on a steel chassis with a zinc dichromate treatment for corrosion resistance, which is what you want in an apartment corridor, school or hotel. If you're cross-shopping other heavy duty passage levers, the Falcon K101 and Falcon T101 are both heavy duty Grade 1 passage cylindricals. For a lighter interior application, the Falcon B101 is a medium duty Grade 2 passage lever.
8) Can I use a Corbin Russwin CL3510 on an apartment unit entry door?
Not for the entry itself. The CL3510 is non-keyed passage function, both levers always free, so it gives no security at a unit door. Use it inside the unit on hall, corridor and closet doors, and put a keyed function on the entry. Commercial keyed alternatives we carry include the Hager 2525 entry lever and the Cal-Royal AG05 storeroom lever with a deadlocking latchbolt.
9) Does the Corbin Russwin CL3510 need a 2-3/4 inch backset, or can it go in a 2-3/8 inch prep?
Standard is a 2-3/4 inch backset, and the standard 600F09 and optional 600F12 latches are both cut for 2-3/4. Corbin Russwin also builds the CL3500 chassis in 2-3/8, 3-3/4 and 5 inch backsets, so a residential-depth 2-3/8 prep or a deep stile can be covered, but the backset is fixed at the order, not adjustable in the field. Measure from the door edge to the center of the bore before ordering.
10) Can I use a dummy lever in place of the Corbin Russwin CL3510?
No, they do different jobs. The CL3510 is a cylindrical passage lock with a working latchbolt retracted by the lever from either side. A dummy has no latch and no chassis, so it will not hold the door closed. If the leaf is inactive or held by a ball catch, the BEST 9K Series 1DT is a Grade 1 heavy-duty single dummy trim, the BEST 7KC Series 1DT is the Grade 2 medium-duty single dummy trim, and the Accentra 455LN Augusta is a Grade 1 heavy-duty single dummy from the 5400 Series.
11) Is there a lighter-duty passage lever lock instead of the Corbin Russwin CL3510?
Yes. The Falcon B101 is a Grade 2 medium-duty cylindrical passage lever lock, also non-handed. The Accentra 5301LN Augusta and the Accentra 4601LN are Grade 2 passage cylindrical lever locks from the 5300 and 4600 Series respectively, and the Hager 2510 is a Grade 2 passage cylindrical lever lock with the Withnell lever design, listed for 1-3/8 inch to 2 inch doors. The CL3510 itself is a Grade 1 heavy-duty set, so these step down the duty rating on interior corridor and closet doors that do not see the same traffic.
12) Is a Kwikset passage lever the same thing as the Corbin Russwin CL3510?
They are not equivalents. The Kwikset 200BRNL Breton passage lever is Grade 3 for 1-3/8 inch to 1-3/4 inch doors, and the Callan Asheville passage leverset is also Grade 3. The CL3510 is a Grade 1 heavy-duty commercial set with a steel chassis that is zinc dichromated for corrosion resistance. All three latch a hall or closet door, but the Grade 3 sets sit two grades below the CL3510 on ANSI/BHMA cycle and strength testing, which is what a spec calling for commercial-grade passage hardware is asking about.
13) Which passage lever locks besides the Corbin Russwin CL3510 carry a Grade 1 rating?
The Design Hardware X75 is a Grade 1 passage lever lockset with a flat lever, built for 1-3/4 inch doors. The Falcon K101 and Falcon T101 are both Grade 1 heavy-duty cylindrical passage lever locks. The CL3510 is Grade 1 for 1-3/8 inch to 1-3/4 inch doors and is fire rated, so on a rated opening confirm the substitute carries the same listing before swapping. The Design Hardware J75 is the Grade 2 version of the same flat-lever passage set.
14) We want keyless code entry on a closet or storage door instead of a plain passage lever. What replaces the CL3510?
The CL3510 is a non-keyed passage set with both levers always free, so it gives no access control at all. For pushbutton code entry with the same lever pull, 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, and the Lockey 2835DC is the double combination version over the same thickness range. The Lockey 1150 is a heavy-duty mechanical keypad lever set with double combination passage function for 1-1/8 inch to 2 inch doors, and the 1150S adds an adjustable backset.
15) The CL3510 uses a lever. What is the knob equivalent for a commercial passage or utility door?
The comparable knob sets change function rather than matching passage. The Arrow MK02-TA is a Grade 1 privacy cylindrical lock with a Tudor knob, fire rated, for 1-3/4 inch to 2 inch doors, and the Arrow MK33-BD-CS is a Grade 2 heavy-duty asylum function cylindrical lock with a ball knob and a Schlage C keyway conventional cylinder. The CL3510 itself is a lever set with Armstrong, Newport, and Princeton lever styles, which is what an ADA-governed opening generally calls for.
