Corbin Russwin CL3570 NZD 626 – Frequently Asked Questions

1) What does the Corbin Russwin CL3570 dummy lever actually do, and where would I use it?
Nothing mechanical. The levers on the CL3570 are rigid and act as a pull only, with no latch operation at all. That makes it the trim you put on an inactive leaf of a pair, on a closet or wardrobe door that is held shut by a ball catch or roller catch, or on any opening where you want the lever to look identical to the working locksets down the hall. If you need the lever to retract a latch, this is the wrong part and you want a passage function instead.
2) Is the CL3570 a single dummy or does it put a lever on both sides of the door?
Double, or full, dummy trim: it dresses both faces of the door with a lever. If you only need one side, say the push side of an inactive leaf, a single dummy is the cheaper way to go, and ZenSupply carries the BEST 9K Series 1DT single dummy trim in heavy duty and the Accentra 455LN Augusta single dummy as Grade 1 alternatives.
3) Will the Corbin Russwin CL3570 fit a 1-3/4 inch commercial door?
Yes. The CL3570 covers doors from 1-3/8 to 1-3/4 inches thick, which spans the standard 1-3/4 inch commercial leaf and the thinner 1-3/8 inch interior doors common in older buildings. Thicker than 1-3/4 inches and you are outside the stated range.
4) Can I use the CL3570 dummy trim on a fire rated door?
The CL3570 carries a fire rating, so it is suitable for a rated opening. Keep in mind that dummy trim does no latching, so on a rated pair the inactive leaf still needs whatever latching and coordinating hardware the assembly calls for. The trim itself is not what holds the door closed.
5) I ordered a Corbin Russwin CL3570 but the door actually needs to latch. What should I use instead?
The CL3570 will not work on that opening: its levers are rigid and act as a pull only, with no operation, so there is no latchbolt to hold the door closed. For a latching non-keyed lever in the same heavy-duty Grade 1 class, 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 cylindrical lever. Both are passage function, so the lever retracts a latch and the door stays shut, while matching the CL3570 on Grade 1, heavy duty, and non-handed installation.
6) What is the difference between a Corbin Russwin CL3570 dummy lever and a passage lever like the Design Hardware X75?
Function. The Design Hardware X75 is a Grade 1 passage lever lockset, so the lever turns and retracts a latch. The Corbin Russwin CL3570 is a dummy: its levers are rigid and act as a pull only, with no operation and nothing to retract. They match on grade, both being Grade 1, and both are lever trim, so the visual match across a run of doors holds. Pick the CL3570 for an inactive leaf or a door held by a ball catch or magnet, and the X75 where the door must latch. Note the door thickness: the X75 is listed for 1-3/4 inch doors, while the CL3570 covers 1-3/8 inch to 1-3/4 inch.
7) I need to lock the door, not just trim it. What Grade 1 lever lock goes with a Corbin Russwin CL3570 on the rest of the openings?
The CL3570 is non-keyed with a dummy function, so it never locks anything. To pair keyed Grade 1 lever locks with it across a building, the Dexter C1000 Series covers the common functions at Grade 1: the C1000 entry/office is a keyed clutching lever for 1-3/8 inch to 1-3/4 inch doors, the C1000 classroom is a keyed clutching classroom lever in the same thickness range, and the C1000 asylum is a Grade 1 asylum function lock for 1-3/8 inch to 2 inch doors. All three overlap the CL3570 door thickness range of 1-3/8 inch to 1-3/4 inch, so the same door prep carries across the run with the CL3570 handling the inactive leaves.
8) Do I have to specify handing when ordering a CL3570 dummy lever?
No. The CL3570 is non-handed, so the same part works on a left or right hand door and you can stock one item for a whole building. Worth knowing if you are comparing against decorative dummies, which often are handed. Baldwin's Estate 5103 half dummy, for example, is ordered as a distinct left hand or right hand part.
9) What lever designs and finishes does the Corbin Russwin CL3570 come in?
Three lever styles, Armstrong (AZD), Newport (NZD) and Princeton (PZD), across fourteen finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 613E dark oxidized satin bronze equivalent, 613L dark oxidized 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. Pick the lever style and finish that match the working locksets already on the job so the dummy leaf reads the same.
10) Will a Corbin Russwin CL3570 dummy lever match my existing CL3500 Series locksets?
It is built as the non-keyed trim member of the CL3500 Series, using the same Armstrong, Newport and Princeton lever designs and the same finish range, so a dummy leaf will match the keyed and passage openings around it. That matching-across-a-fleet job is the main reason to buy dummy trim from the same series rather than a generic dummy.
11) Does the CL3570 dummy lever take a key or a cylinder?
No cylinder and no keyway. The CL3570 is non-keyed, so it cannot be keyed into a master system and there is nothing to rekey. If someone on the job asked for a dummy that could later be converted to keyed, they need a different function entirely, not this trim.
12) I need a lever that actually opens the door, not a dummy. What should I order instead?
Then skip dummy trim and buy a passage function. Among heavy duty Grade 1 options ZenSupply carries the Falcon K101, which is non-handed and fire rated for doors 1-3/8 to 2-1/4 inches thick, and the Falcon T101 heavy duty passage lever. For a Grade 2 commercial passage lever, the Hager 2510 covers 1-3/8 to 2 inch doors and the Accentra 5301LN Augusta is another option.
13) Does a dummy lever need a latch, strike, or door prep beyond the cross bore?
There is no latch and no strike involved, because the levers do not operate anything. The trim mounts to the door face, so what you need at the opening is a catch or a flush bolt to actually hold the leaf shut. Order that separately; the dummy trim is the pull and the appearance, nothing more.
14) Can I use an Accentra 455LN Augusta dummy lever in place of a Corbin Russwin CL3570?
Functionally yes, with one coverage difference. The Accentra 455LN Augusta is a heavy-duty Grade 1 single dummy cylindrical lever lock from the 5400 Series, matching the Corbin Russwin CL3570 on grade, duty level, and dummy function. The CL3570 is double/full dummy trim covering both faces of a leaf, while the 455LN is single dummy for one face. Trim design also differs: the 455LN is the Augusta lever, where the CL3570 is ordered with an Armstrong, Newport, or Princeton lever. If the goal is matching lever appearance to Corbin Russwin trim already hung elsewhere in the building, the lever style is the deciding detail.
15) Is there a lighter-duty dummy lever that matches a Corbin Russwin CL3570 on a low-traffic interior door?
The BEST 7KC Series single dummy trim covers the same job at a lower duty rating: it is a Grade 2 medium-duty non-keyed dummy cylindrical lever trim, where the Corbin Russwin CL3570 is Grade 1 heavy duty. The Callan Bentley BN5051 is another Grade 2 dummy lever. Both act as pulls with no latch operation, the same as the CL3570, whose levers are rigid and act as a pull only. Where the CL3570 differs is fire door use: it carries a fire rating, so on a rated opening in a corridor or stair enclosure, keep the CL3570 rather than dropping to a Grade 2 trim.
16) Are the Baldwin Estate 5103 half dummy levers an alternative to a Corbin Russwin CL3570?
They serve the same no-operation purpose but differ in two ways that decide the order. The Baldwin Estate 5103 half dummy is offered as a left hand unit and a separate right hand unit, so you specify the hand of the door when ordering. The Corbin Russwin CL3570 is non-handed, so one part number covers either swing, which is what you want when standardizing a fleet of openings without tracking handing per door. The 5103 is also a half dummy, one face only, where the CL3570 is double/full dummy trim for both faces. For a commercial or institutional opening the CL3570 carries a Grade 1 commercial rating and a fire rating.
17) What is the difference between the Emtek Arts and Crafts dummy pair and a Corbin Russwin CL3570 for a dummy lever on a double door?
Both give you a lever on each face with no latch operation. The Emtek Arts and Crafts leverset dummy pair and the Emtek Cortina dummy pair are sold as dummy pairs in decorative lever designs. The Corbin Russwin CL3570 is double/full dummy trim built for commercial service: Grade 1, heavy duty, fire rated, on a steel substrate that is zinc dichromated for corrosion resistance. For a residential or boutique interior where the trim design carries the room, the Emtek pairs are the design-led choice; for a corridor, apartment building, or institutional opening where the trim has to hold up and match a rated assembly, the CL3570 is the one specified.
18) Does a keypad lever like the Lockey 2835 or Delaney LP250 replace a Corbin Russwin CL3570?
No, they answer opposite requirements. The Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function, fitting doors 1 3/16 inch to 2 inch, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Both control who gets through the door. The Corbin Russwin CL3570 is non-keyed dummy trim whose levers are rigid and act as a pull only, so it controls nothing. On a paired opening, these often go on the same job rather than one replacing the other: the access-controlled lever on the active leaf, the CL3570 on the inactive leaf for matching appearance.
19) Is this dummy lever heavy enough for an apartment building or a school corridor?
It is a commercial, heavy duty cylindrical trim built on a steel substrate with a zinc dichromate treatment for corrosion resistance, which is a different animal from a residential decorative dummy. For lighter interior use where the look matters more than the traffic, ZenSupply also carries medium duty and residential-style dummies such as the BEST 7KC Series single dummy trim and the Emtek Classic Cortina dummy pair.
20) For a residential-grade interior door, is a Kwikset lever a substitute for a Corbin Russwin CL3570?
They are built for different service levels. The Kwikset 200BRNL Breton passage lever is Grade 3 and covers 1-3/8 inch to 1-3/4 inch doors, and the Kwikset 300BRNL Breton privacy lever is Grade 3 in the same thickness range. The Corbin Russwin CL3570 is a commercial Grade 1 heavy-duty trim in a 1-3/8 inch to 1-3/4 inch range. The Kwikset units are also operating locks, passage and privacy, where the CL3570 levers act as a pull only with no operation. On an apartment interior door that only needs a pull, the CL3570 is the commercial-duty answer; the Kwikset levers answer a different need on the same door.
21) Which dummy lever should I pick if I want a Grade 2 option that still looks like the rest of a commercial lever run?
The Callan Bentley BN5051 is a Grade 2 dummy lever, and the BEST 7KC Series single dummy trim is a Grade 2 medium-duty non-keyed dummy cylindrical lever trim. Both give a rigid lever pull with no operation, the same behavior as the Corbin Russwin CL3570. Where the CL3570 separates itself for appearance matching is finish and lever breadth: it is ordered in fourteen finishes including 626 satin chrome, 613 satin bronze oil-rubbed, and 619 satin nickel, with an Armstrong, Newport, or Princeton lever. If the existing doors carry a specific Corbin Russwin lever profile, matching it is the reason to stay with the CL3570.
