Corbin Russwin A855ET 626 RHR – Frequently Asked Questions

1) Which types of exit devices will this Corbin Russwin classroom lever trim work with?
It mounts to Rim, Surface Vertical Rod, and Concealed Vertical Rod ED4000 Series devices, including the SecureBolt configuration. One trim part number covers all three device styles, which is useful when a building has a mix of single doors on rim devices and pairs on vertical rod devices and you want the same lever on every opening.
2) Do I have to specify handing when ordering this Corbin Russwin classroom lever trim?
Yes. The exit devices themselves are non-handed, but lever trim is handed, and this trim is ordered LHR (left hand reverse) or RHR (right hand reverse). Exit device trim is always a reverse hand because the door swings out under you. Stand outside the door: if the hinges are on your right and the door pulls toward you, it is RHR.
3) Is a cylinder included with the x855ET classroom trim, and what kind do I need?
The trim is ordered less cylinder as standard, or with a conventional 6-pin or 7-pin cylinder. The cylinder classification is rim, so the keyed side takes a rim cylinder rather than a mortise cylinder. If you are matching an existing master key system, order less cylinder and fit your own. Keying is available keyed different or keyed alike when you want a set of classroom doors on one key.
4) What door thickness does the ED4000 Series classroom trim fit?
Standard is 1-3/4 inch (44mm), which covers most commercial hollow metal and wood doors. Thicker openings are handled with options: 2 inch (D200) or 2-1/4 inch (D214). Specify the thickness option at order time, since the through-bolt hardware has to match the door.
5) Is this classroom trim ADA compliant for a school or healthcare corridor?
Yes. The lever trim on the ED4000 Series is ADA compliant, so it satisfies the requirement for operation without tight grasping or twisting of the wrist. The devices it pairs with are UL/cUL listed panic and 3-hour fire exit hardware and comply with NFPA 101 and NFPA 80, and they carry California State Fire Marshal approval.
6) What is the closest classroom-function lever exit trim to the Corbin Russwin x855ET from another brand?
The Corbin Russwin x855ET ED4000 trim is a classroom-function lever trim. For classroom function from other manufacturers, the Accentra 446F pairs an Augusta lever escutcheon trim with Grade 1 classroom function, and the Falcon 510L is a heavy duty classroom-function exit device trim with a lever handle for 24/25 Series devices. The Falcon 179L is also classroom function but is a medium duty lever control trim for 1790 Series devices. The x855ET remains the choice when the device is a Corbin Russwin ED4000 Rim, Surface Vertical Rod or Concealed Vertical Rod unit.
7) I need storeroom function instead of classroom on an exit device - what should I order?
The Corbin Russwin x855ET is built for ANSI Function 08 classroom operation, where a key locks and unlocks the lever from the outside. If the opening calls for storeroom function, where the lever is always locked and the key retracts the latch, look at the Design Hardware KIL storeroom trim for 1000 and 2000 Series devices with a Schlage C keyway flat lever, the Tell EDELT80 escutcheon lever trim in storeroom function, the Pamex E9000 Grade 1 storeroom trim with L3 lever, or the Marks USA M195F storeroom lever and rose trim for M9900 touchbar devices.
8) Is a night latch trim the same thing as the classroom trim on a Corbin Russwin ED4000?
No. The Corbin Russwin x855ET gives classroom operation, where the lever is a normal operating lever that a key locks and unlocks from the outside. Night latch trim keeps the outside lever or pull inoperative and uses the key only to retract the latch. Night latch options include the Sargent 704ET field reversible lever trim, the Sargent 744 freewheeling trim for 8700 and 8900 Series surface vertical rod and mortise devices, the Dorma YR03R wide stile escutcheon lever trim, and the Accentra 121NL pull trim. Those will not give you the lockable, unlockable outside lever a classroom opening usually needs.
9) We want the outside lever released by an access control system - is there an electrified alternative to the x855ET?
The Corbin Russwin x855ET is mechanical classroom trim keyed from the outside. For electrified control of the outside lever, Command Access offers the ET15, ET25 and ET26 electrified exit trims with 12V/24V operation and fail safe or fail secure options, with the ET26 built to Grade 1 with a field reversible design, plus the 230L electrified trim for Von Duprin 98/99, 33/35 and 22 style devices. Falcon offers the 510L-FSA/FSE electrified heavy duty lever trim for 25 Series devices, and Von Duprin the E360L-BE-03 Grade 1 electric passage trim with 03 lever, fail safe, for 33/35A Series.
10) What happens if someone yanks or hangs on the lever when the trim is locked?
The levers are free wheeling for vandal resistance. When the trim is locked, the lever rotates without engaging the mechanism, so force applied to the handle does not transfer into the chassis. That matters on school and dormitory corridors where locked levers take abuse. The chassis itself is cold-forged steel with an electroplated corrosion-resistant finish.
11) What lever and escutcheon designs does the Corbin Russwin x855ET come in?
Eight escutcheon trim designs: A9 Armstrong, C9 Citation, D9 Dirke, E9 Essex, L9 Lustra, N9 Newport, PR9 Princeton and R9 Regis. Fourteen finishes run from 605 bright brass and 606 satin brass through 613 and 613E oil-rubbed bronzes, 618/619 nickels, 625/626 chromes, 629/630 stainless, 722 black oxidized bronze and BSP black suede powder coat. If you are matching existing Corbin Russwin openings in a building, match the design letter and the finish number, not just the color name.
12) Will the latch on a rim ED4000 device engage my existing strike?
The rim device uses a stainless steel pullman-type latchbolt with a 3/4 inch (19mm) throw and a deadlocking auxiliary latch, and it is supplied with a surface-mounted 3/8 inch roller strike with a positive locking plate and shims. The shims let you take up gap variation on the frame. If you are replacing a different brand's rim device, plan on using the supplied strike rather than the old one, since strike geometry is not interchangeable between manufacturers.
13) What is the difference between the standard rim latch and the SecureBolt option?
The standard rim latch (ED5200) is a pullman-type stainless bolt with 3/4 inch throw and a deadlocking auxiliary latch. The SecureBolt option (ED5200S) substitutes a deadbolt-style latchbolt, 3/4 inch projection by 1 inch wide, positively deadlocked by an auxiliary bolt. Choose SecureBolt where the opening is exposed and you want resistance to prying or loiding rather than a standard beveled latch.
14) I need the outside lever controlled by an access control system. Is there an option?
The ED4000 platform offers electrified options including delayed egress, electric latch retraction and electric dogging, so the opening can be driven from a card reader or a remote release. If you are retrofitting electrification onto a different brand's device instead, Command Access builds drop-in electrified exit trim such as the ET15, ET25 and ET26, and the 230L for Von Duprin 22/33/98 series devices, all with 12V/24V operation and fail safe or fail secure selection.
15) Should I order classroom function trim or storeroom function trim for a corridor door?
Classroom function, which is what the x855ET provides, lets a key lock and unlock the outside lever so the door can be left unlocked during the day and secured with a key. Storeroom function keeps the outside lever locked at all times and the key only retracts the latch for entry, with no way to leave it unsecured. If you want the door permanently locked from outside, look at storeroom trim such as the Marks USA M195F or the Design Hardware KIL storeroom trim for 1000 and 2000 Series devices. Night latch trim, like the Sargent 704ET, is key-retract only with no lever control.
16) What grade is the Corbin Russwin ED4000 Series, and is it heavy enough for a high traffic school entrance?
ANSI/BHMA A156.3 Grade 1, the highest grade for exit devices and the level normally specified for schools, healthcare and government buildings. Grade 1 commercial rating means the hardware is built for high cycle counts on doors that see constant use.
17) How does the vertical rod version latch a pair of doors without a mullion?
A surface vertical rod ED5400 device latches at the head and the sill instead of into a center strike, so a pair of doors can be secured with no removable mullion between them. The top latch is a 3/4 inch throw pullman with deadlocking, and the bottom is a 5/8 inch throw deadbolt into the threshold. The same x855ET classroom trim mounts to the SVR device, so both leaves of a pair can carry matching levers.
18) Does a heavy duty rating matter when choosing between the x855ET and a Falcon lever trim?
The Corbin Russwin ED4000 Series trim is built to ANSI/BHMA A156.3 Grade 1. On the Falcon side, the 510L classroom lever trim for 24/25 Series devices is rated heavy duty while the 179L lever control trim for 1790 Series devices is medium duty. Sargent 704-ETL and 704ET lever trims are heavy duty Grade 1 but night latch function. For a high traffic school corridor, match both the duty level and the classroom function rather than function alone.
19) The opening needs a thumbpiece or pull rather than a lever - what replaces the x855ET?
The Corbin Russwin x855ET is lever trim in eight escutcheon designs from Armstrong through Regis. Where a lever will not suit, the Dexter ED1000T-CLRM-TP-NC gives classroom function with a thumbpiece, pull plate and cylinder prep supplied less cylinder, and the Tell EDTHP53 is an entry function thumbpiece trim. For straight pulls with cylinder prep, consider the Tell EDPT pull trim less cylinder, the Design Hardware 2P-03NL night latch pull trim with cylinder hole for 1000R and 2000R devices, or the Dexter ED1500 raised lip pull plate nightlatch trim. Note the x855ET is ADA compliant lever trim, which a thumbpiece design may not match.
20) Is there a keypad or credential trim option instead of a keyed classroom lever trim?
The Corbin Russwin x855ET uses a rim cylinder for key control of the lever. If you would rather manage codes than keys on the same style of opening, Dormakaba offers the E-Plex 201U electronic pushbutton exit trim for wide stile doors and the PowerPlex P201U exit trim for rim, mortise and surface vertical rod devices. Those change how the door is credentialed, so confirm the trim matches the exit device family already on the door before ordering.
21) Will a blank escutcheon or knob trim work in place of the Corbin Russwin classroom lever trim?
Not for a classroom opening. The Corbin Russwin x855ET is ADA compliant classroom lever trim with key entry. The Falcon 212L is a 20 Series blank escutcheon lever trim with shear pin protection, and the Von Duprin 210K-BE is a knob with blank escutcheon for 22 Series devices - blank escutcheon means no cylinder prep, so there is no outside key control, and a knob does not carry the same ADA compliance the lever trim does. Use those only where the outside side is meant to stay unkeyed.
22) How far does the trim and device project off the face of the door?
Projection is 3-1/4 inches (83mm) with the device active and 2-3/4 inches (70mm) when dogged down. Check that against clearance in a tight vestibule or where a door swings toward a wall or another leaf. Dogging is standard single-point 1/4 turn hex key, with cylinder dogging or electric dogging available as options (dogging is not permitted on fire rated openings).
23) Do I need a different push bar length for a 30 inch door versus a 48 inch door?
The standard bar is 36 inches and fits doors from 30 to 36 inches wide, and it can be field cut. For openings outside that range, 24 inch and 48 inch bars are the options. Measure the leaf width before ordering, since the bar length is set at the device, not the trim.
24) Can I add night latch key control to an existing device instead of replacing the whole trim?
The Corbin Russwin x855ET is a full escutcheon lever trim that mounts as an assembly and carries the classroom lever. If all the opening needs is outside key retraction on a Von Duprin 22, 55 or 98/99 device, the Von Duprin 110MD-NL is a night latch cylinder assembly for metal and wood doors rather than a lever escutcheon. That changes the operation to night latch, so it is not a swap for classroom lever trim on a Corbin Russwin ED4000 device.
