Corbin Russwin CL3550-NONKEYED Single/Half Dummy Trim Heavy-Duty Grade 1 Cylindrical Lever Lock, Non-Keyed

Commercial-Grade Dummy Lever Trim for Consistent Aesthetics Across the CL3500 Series

The Corbin Russwin CL3550 Single/Half Dummy Trim is a heavy-duty, non-keyed cylindrical lever lock designed for commercial, institutional, and multi-family applications where a rigid pull-only lever is required. The lever acts as a pull only with no operational function, making it ideal for paired door applications and aesthetic continuity. Engineered to accommodate door thicknesses of 1-3/8" to 1-3/4" with a 2-3/4" backset, this ANSI/BHMA Grade 1 certified lockset is built from solid cast levers and steel substrate with zinc dichromate treatment for corrosion resistance. The most common configuration features the NZD Newport lever in a 626 Satin Chrome finish.

Corbin Russwin CL3550 NZD 626 – Frequently Asked Questions

1) Does the lever on the Corbin Russwin CL3550 actually turn, or is it fixed?
It's fixed. The CL3550 is a dummy trim, so the lever is rigid and acts as a pull only, with no operation. There is no latchbolt, no spindle action and nothing to retract, so it gets mounted on a door that is held shut by a catch, a magnet, or the active leaf of a pair. If you need the lever to retract a latch, you want a passage function instead.
2) Will the CL3550 dummy lever fit a 1-3/4 inch commercial door?
Yes. The CL3550 covers door thicknesses from 1-3/8 to 1-3/4 inches, which spans the standard 1-3/4 inch commercial door and the thinner 1-3/8 inch interior doors common in older buildings.
3) Do I have to order a left hand or right hand version of this Corbin Russwin dummy lever?
No handing to specify. The CL3550 is non-handed, so one part number works on either a left or right hand door. That's a real difference from some decorative half dummies, like the Baldwin Estate 5103, which is sold as separate left hand and right hand versions.
4) I need a dummy lever that matches the other locks on my building's doors. Does the CL3550 match the rest of the CL3500 series?
That's exactly what it's for. The CL3550 is the dummy trim within the Corbin Russwin CL3500 cylindrical series, so it carries the same lever designs and finishes as the keyed and passage functions on the rest of your openings. You pick the lever style, AZD Armstrong, NZD Newport, or PZD Princeton, and match the finish to what's already installed. For a property manager standardizing a floor or a whole building, order the CL3550 in the same lever and finish code as the working locks.
5) What is the closest heavy-duty equivalent to the Corbin Russwin CL3550 single dummy lever from another manufacturer?
The BEST 9K Series 1DT is the closest heavy-duty match. Like the CL3550, it is a non-keyed single dummy trim cylindrical lever lock rated Grade 1 and classified heavy duty. Both put a rigid lever on the door that serves as a pull only with no latch operation, so either one works for the inactive leaf of a pair or a false-door application where you want the lever to match the working openings nearby.
6) I need the lever to actually retract a latch - what should I order instead of the Corbin Russwin CL3550?
The CL3550 lever is rigid and acts as a pull only with no operation, so it never retracts a latch. For a non-keyed lever that does operate a latchbolt, look at a passage function lockset: the Falcon K101 is a Grade 1 heavy-duty passage cylindrical lock with non-handed levers and a fire rating, and the Falcon T101 is a Grade 1 heavy-duty passage lever. The Dexter C1000 passage is also Grade 1 with clutching, non-keyed levers. Any of those gives you a working latch on a door that does not need to lock.
7) The opening needs a key - can I use the Corbin Russwin CL3550 with a cylinder?
No. The CL3550 is a non-keyed dummy, with no chassis and no cylinder. For a keyed cylindrical lever on the same style of opening, the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt, the Hager 2580 is a Grade 2 storeroom lock with the Withnell lever, and the Dexter C1000 classroom is a Grade 1 keyed clutching lever. Choose by function: storeroom stays locked outside, classroom is keyed from the outside to unlock.
8) What are the commercial alternatives to the Corbin Russwin CL3550 dummy lever?
Two close cross-brand equivalents sit in the same lane. The BEST 9K Series 1DT is a heavy duty single dummy trim cylindrical lever, and the Accentra 455LN Augusta is a heavy duty single dummy cylindrical lever from the 5400 Series. Both are, like the CL3550, heavy duty cylindrical dummy trims rather than decorative ones. If your building is already standardized on a keyway or lever design from one of those lines, pick the matching brand so the dummy openings look like the rest.
9) Can I use a cylindrical dummy trim like the CL3550 on a fire rated door?
The CL3550 is fire rated. Bear in mind a dummy trim has no latch, so on a fire door it is only ever used on the inactive leaf of a pair where a separate latching or flush bolt arrangement holds that leaf, never as the sole hardware on a single fire door opening.
10) Is the CL3550 a two-sided dummy, or just one side of the door?
One side. It's a single, or half, dummy trim, so one unit covers one face of the door. For a double door where you want a pull on both faces, order two. If you'd rather buy a matched pair as a single item, Emtek sells its Arts and Crafts and Classic leversets in dummy pair form, though those are decorative residential-style trims rather than commercial cylindrical hardware.
11) Does the CL3550 dummy lever need a key or a cylinder?
No cylinder, no key. The CL3550 is a non-keyed dummy trim, which means there's nothing to key into a master system and no cylinder to order or supply. If the opening needs to lock, you're looking at the wrong function entirely, and a keyed cylindrical lever from the CL3500 line is what belongs there instead.
12) Is there a lighter-duty dummy lever I can use instead of the Corbin Russwin CL3550 on low-traffic interior doors?
Two step down from the CL3550's heavy-duty Grade 1 build. The BEST 7KC Series single dummy trim is a Grade 2 medium-duty cylindrical lever dummy, and the Callan Bentley is a Grade 2 dummy lever. Both perform the same pull-only function as the CL3550 but at a lower ANSI/BHMA grade, which suits closet fronts, offices, and interior openings that see light use rather than institutional corridors.
13) What is the difference between the Corbin Russwin CL3550 dummy and the Accentra 455LN Augusta dummy?
Both are Grade 1 single dummy cylindrical lever locks, so they serve the same pull-only role. The difference is trim family and lever style: the Accentra 455LN carries the Augusta lever design in the 5400 Series, while the CL3550 is CL3500 Series trim offered with the Armstrong, Newport, or Princeton lever. Pick the one that matches the working locksets already hung on the adjacent doors so the dummy leaf does not read as an odd part.
14) Is a Baldwin 5103 half dummy the same thing as a Corbin Russwin CL3550?
Same function, different build and ordering. Both are half dummy levers that act as a pull. The Baldwin Estate 5103 half dummy is handed and ordered as a left hand or right hand item with the 5048 rose, while the CL3550 is non-handed, so one part number covers either leaf. The CL3550 is also a commercial Grade 1 cylindrical trim on a zinc dichromated steel substrate, which is the reason it turns up on institutional and multi-family work rather than residential-decorative openings.
15) I need dummy levers on both sides of a door - does the Corbin Russwin CL3550 cover that?
The CL3550 is a single or half dummy, meaning one lever on one face. For trim on both faces of a leaf, dummy pairs are sold as such: Emtek offers the Arts and Crafts lever and the Hammered lever as dummy pairs, and the Classic Brass Cortina lever is also a dummy pair. Ordering two CL3550 units is the other route if you want to stay in commercial Grade 1 trim on both faces.
16) Which passage lever should I pair with the Corbin Russwin CL3550 on the active leaf of a pair of doors?
The CL3550 dummy typically goes on the inactive leaf while a functioning lockset handles the active one. For a Grade 1 non-keyed match in duty level, the Falcon K101 is a heavy-duty passage cylindrical lock with non-handed levers and a fire rating, and the Design Hardware X75 is a Grade 1 passage lever lockset for 1-3/4 inch doors. If the active leaf is lower traffic, the Accentra 4601LN and 5301LN are Grade 2 passage cylindrical levers.
17) My door is thicker than 1-3/4 inches - is the Corbin Russwin CL3550 still the right dummy lever?
The CL3550 is specified for 1-3/8 inch to 1-3/4 inch doors. If the leaf is thicker and you need a lever with an operating latch rather than a dummy, the Falcon K101 covers 1-3/8 inch to 2-1/4 inch and the Dexter C1000 asylum covers 1-3/8 inch to 2 inch, while the Arrow GL01 passage lever is built for 1-3/4 inch to 2 inch doors. Confirm the leaf thickness at the bore before you commit either way.
18) Can a Kwikset or Callan passage lever substitute for the Corbin Russwin CL3550 in a commercial building?
They are not a like-for-like swap. The CL3550 is a commercial heavy-duty Grade 1 lever. The Kwikset 200BRNL Breton passage lever and the Callan Asheville passage leverset are both Grade 3, and the Callan Artino entrance leverset is Grade 3 as well. Grade 3 products are built to a residential cycle and strength standard, so on an institutional or multi-family corridor spec they will not carry the same rating.
19) The door needs a privacy lock, not a dummy - what replaces the Corbin Russwin CL3550 there?
A dummy like the CL3550 has no operation at all, so it cannot serve a restroom or bedroom. For a privacy function, the Hager 2540 uses the Withnell lever and covers 1-3/8 inch to 2 inch doors, and the Baldwin 5103 privacy lever with the 5048 rose is the option in a decorative trim. If a knob is acceptable, the Arrow MK02-TA is a non-keyed privacy cylindrical lock that is fire rated.
20) Is the CL3550 lever going to hold up in an apartment building or a school corridor?
It's a heavy duty commercial trim, built on a steel substrate with a zinc dichromate treatment for corrosion resistance, and the levers are solid cast with no plastic inserts. Since a dummy has no moving chassis, the failure mode on cheaper dummies is usually the lever pulling loose or sagging, which is where the cast lever and through-bolted mounting matter in high-traffic multi-family, education and healthcare openings.
21) We are standardizing a facility on one lever look - does the Corbin Russwin CL3550 give more finish choices than the comparable dummy levers?
The CL3550 dummy trim is offered in 14 finishes, from 605 Bright Brass and 626 Satin Chrome through 613 Satin Bronze Oil-Rubbed, 722 Black Oxidized Bronze Oil-Rubbed, and BSP Black Suede and WSP White Suede powder coat, across three lever styles. That breadth is what lets the dummy leaves match keyed and passage openings across a building. Among the Grade 1 dummy alternatives, the BEST 9K 1DT and the Accentra 455LN Augusta are the peers to check against your existing trim if you are already standardized on one of those lines.
22) Would a keypad lever work in place of the Corbin Russwin CL3550 for controlled access?
No, and not because of the trim style. The CL3550 is a dummy with no latch and no credential of any kind. If the opening actually needs coded access, 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 1150 is a heavy-duty mechanical keypad lever set for 1-1/8 inch to 2 inch doors, and the Delaney LP250 is an electronic keypad leverlock rated Grade 2.
