Corbin Russwin A3355ET 626 RHR – Frequently Asked Questions

1) What does classroom function mean on this exit trim, and how does it behave day to day?
Classroom function here is ANSI Function #08: the outside lever stays free at all times until it is locked by key from the outside. Nobody gets locked in, since the push bar always retracts the latch from the inside, and a teacher can lock the corridor side with a key without opening the door. If you want the outside lever locked all the time with key access only, that is a storeroom function trim instead, like the Design Hardware KIL Storeroom trim or the Tell EDELT80.
2) Do I have to specify handing when I order the ED3000 classroom lever trim?
Yes. The ED3000 devices themselves are non-handed, but lever trim and double cylinder devices are handed, so this trim is ordered LHR (left hand reverse) or RHR (right hand reverse). Stand outside the door: if the hinges are on your right and the door pushes away from you, that is RHR. Get it wrong and the lever points the wrong way.
3) Does a cylinder come with the Corbin Russwin 3355ET classroom trim, or do I order it separately?
Standard is less cylinder. You choose either less cylinder (to supply your own or use an existing keyed system), a conventional 6-pin, or a conventional 7-pin. If you go with a factory cylinder you also pick keying: KD keyed different is standard, KA keyed alike if you want a group of classrooms on one key. The cylinder used is a rim cylinder.
4) Will this classroom trim work on a 1-3/4 inch door, and what about thicker doors?
1-3/4 inch (44mm) is the standard door thickness for the ED3000 Series, which covers the great majority of commercial openings. Thicker doors are handled by option: D200 for 2 inch and D214 for 2-1/4 inch. Minimum stile width is 4-1/2 inch (114mm), so this is wide stile hardware, not something to put on a narrow aluminum storefront stile.
5) Is this classroom trim ADA compliant and fire rated?
ADA compliant, yes, the lever trims and pulls meet the Americans with Disabilities Act requirements. On the fire side the ED3000 Series hardware is UL/cUL listed for panic and 3-hour fire exit hardware and complies with NFPA 101 and NFPA 80, plus California State Fire Marshal approval. It is ANSI/BHMA A156.3 Grade 1.
6) What is the closest classroom function lever exit trim to the Corbin Russwin 3355ET from another brand?
The Falcon 510L is the nearest match. Both are classroom function lever exit device trims, and the Falcon 510L is a heavy duty trim in the 24/25 Series. The Corbin Russwin 3355ET is built for ED3255, ED3455, and ED3655 rim, surface vertical rod, and mortise devices and is ANSI Function #08, free at all times except when locked by key. The Accentra 446F is another classroom function lever exit trim with the Augusta lever design. Match the trim to the exit device chassis family you already have on the door.
7) I need key-retracts-latch operation instead of classroom function on my exit device - what trim should I use?
Night latch trim is the function you want. The Sargent 744 is a Grade 1 night latch trim with freewheeling lever where the key retracts the latch, for 8700 and 8900 Series surface vertical rod and mortise devices, and the Sargent 704ET is a night latch lever trim with field reversible operation. The Corbin Russwin 3355ET is a classroom function trim instead - the lever is free at all times except when locked by key, so the outside lever stays operable rather than being permanently locked with key-only retraction.
8) What is the difference between the Corbin Russwin 3355ET and a storeroom function exit trim?
Function is the difference, not construction. The Corbin Russwin 3355ET is ANSI Function #08 classroom: the lever is free at all times except when locked by key. Storeroom trims such as the Design Hardware KIL Storeroom, the Tell EDELT80 escutcheon lever trim, the Marks USA M195F lever/rose trim, and the Pamex E9000 with L3 lever keep the outside lever locked at all times and require the key on every entry. Choose classroom where staff need to lock and unlock the outside lever with a key and leave it unlocked between.
9) Will this trim latch into my existing strike on a rim device opening?
The rim device it pairs with (ED5200) uses a stainless steel pullman latchbolt with a 3/4 inch (19mm) throw and a deadlocking auxiliary latch, and the series ships with a surface-mounted 3/8 inch roller strike including a positive locking plate and shims. Trim does not change latching, so if the existing strike is the same surface roller type set for a 3/4 inch throw you are fine; otherwise use the strike supplied with the device.
10) Will the lever break if someone hangs on it or kicks it while locked?
The levers are free wheeling for vandal resistance, so when the trim is locked the lever spins without driving anything internally. That is the usual failure point on school corridor doors, and it is why free wheeling trim gets specified for high abuse openings. The trim is also thru-bolted to the door rather than surface screwed.
11) What lever and escutcheon designs can I get, and will they match the rest of my building?
Seven escutcheon trim designs are offered: A33 Armstrong, C33 Citation, D33 Dirke, L33 Lustra, N33 Newport, PR33 Princeton, and R33 Regis. Finishes run 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil-rubbed satin bronze, 613E dark oxidized satin bronze equivalent, 618 bright nickel, 619 satin nickel, 625 bright chrome, and 626 satin chrome. Satin chrome (626) is the common institutional standard if you are matching existing corridor hardware.
12) Can I dog the push bar down so the door stays free during school hours?
Standard on the panic devices is single-point 1/4-turn hex key dogging, with cylinder dogging or electric dogging as options. Note that dogging is only available on non-fire-rated panic devices, not on fire exit hardware, so on a rated classroom door the key-locked classroom trim is how you control access instead.
13) What is the difference between this classroom trim and a night latch trim?
Classroom trim (ANSI #08) leaves the outside lever free until a key locks it, so the door can be left unlocked for normal traffic. Night latch trim keeps the outside secured and the key only retracts the latch for entry, with no free lever, such as the Sargent 704ET or the Dormakaba YR03R. If your door should never let anyone in without a key, night latch or storeroom is the right choice. If staff need to switch the opening between open and secure, classroom is.
14) Is there a medium duty alternative to the Corbin Russwin 3355ET classroom trim?
The Falcon 179L is a medium duty classroom function lever control trim for 1790 Series devices, versus the Falcon 510L which is the heavy duty classroom trim. The Corbin Russwin 3355ET is an ANSI/BHMA A156.3 Grade 1 trim built on a cold-forged steel chassis for ED3255, ED3455, and ED3655 devices, which is what most school and healthcare corridor specs call for.
15) Can I use a thumbpiece or pull trim in place of the 3355ET classroom lever trim?
Only if the opening does not need an ADA lever. The Dexter ED1000T-CLRM-TP-NC is a Grade 1 classroom function trim with thumbpiece, pull plate and cylinder prep, less cylinder, and the Tell EDTHP53 is a thumbpiece trim in entry function. The Corbin Russwin 3355ET is ADA compliant lever trim, which is generally what is specified for classroom and institutional openings where a thumbpiece will not satisfy the accessibility requirement.
16) Which exit trims look like a substitute for the 3355ET but are not?
Three to watch. The Falcon 212L is a blank escutcheon lever trim in the 20 Series with shear pin protection, so it has no keyed control at all. The Von Duprin 210K-BE is a knob with blank escutcheon, again unkeyed and not an ADA lever. The Detex 02BN is a dummy S-lever trim with blank escutcheon and does not operate the device. The Corbin Russwin 3355ET is a keyed classroom lever trim that takes a rim cylinder, so none of these replace it on a keyed opening.
17) We are standardizing a building on one lever design and finish - how does the 3355ET compare to other trims on options?
The Corbin Russwin 3355ET is offered in seven escutcheon lever designs - A33 Armstrong, C33 Citation, D33 Dirke, L33 Lustra, N33 Newport, PR33 Princeton, and R33 Regis - across ten finishes from 605 bright brass through 626 satin chrome. By comparison, the Accentra 426F and 441F carry the Augusta lever design and the Delaney 500L comes in CT, MD, and SD lever styles. If you are matching levers across an entire facility, the breadth of the 3355ET design and finish range is the practical reason to standardize on it.
18) What do I use if the opening needs pushbutton or credential access rather than a key?
Move to an electronic exit trim. The Dormakaba E-Plex 201U is an electronic pushbutton exit trim in the E-Plex 2000 Series for wide stile doors, and the Dormakaba PowerPlex P201U is an exit trim for rim, mortise, and SVR devices. Both cover the same device types as the Corbin Russwin 3355ET, which is a mechanical classroom trim operated by a rim cylinder key.
19) How much does this trim stick out from the door face?
Projection on the ED3000 device is 3-1/4 inch (83mm) with the bar active and 2-3/4 inch (70mm) when dogged. That matters where the door swings past a wall return, a column, or another leaf in a vestibule, so check your clearance before setting the opening.
20) If I am also buying the exit device, does the push bar need cutting for my door width?
The ED3000 bar ships 36 inch as standard, which covers 30 to 36 inch doors, and it field cuts easily. Optional 24 inch and 48 inch bars are available for narrower or wider leaves. That is a device-side decision, not a trim one, so the classroom trim itself is the same regardless of bar length.
