Corbin Russwin A555ET 626 – Frequently Asked Questions

1) Will the Corbin Russwin x555ET lever trim work on my ED2200 or ED2400 exit device?

The x555ET classroom lever trim is built for the Corbin Russwin ED2200 and ED2400 Series exit devices, with a rose rather than a full escutcheon. For 7'0" openings it pairs with ED2400 devices; for 8'0" doors you want the ED2400A version of the device. It will not mount to another manufacturer's device, so if the device on the door is a Von Duprin or Sargent, the trim has to match that brand's line.

2) What does classroom function mean on an exit device lever trim, and is it the right choice for a school corridor door?

Classroom function here means entrance by the lever, with the key locking or unlocking that lever from the outside. Nobody is ever locked in: the push bar on the inside always retracts the latch for free egress. That is what makes it standard on classroom and corridor doors where staff needs to secure the outside face without touching the egress side. If you want the outside lever locked at all times with the key retracting the latch only for entry, a storeroom trim is the other common pick.

3) Is the x555ET lever trim handed, or can I order one part for both left and right doors?

Lever trim is the exception to Corbin Russwin's non-handed exit device line. The ED2200/ED2400 devices themselves are non-handed, but lever trim and double cylinder devices are handed, so you need to establish the swing before ordering. Stand outside the door on the key side: if the hinges are on your left it is a left hand door. Ordering one part number for a mixed set of openings will leave you with levers pointing the wrong way.

4) Do I have to order a cylinder separately with the x555ET classroom trim?

Yes, the cylinder is a separate decision. The classroom trim ships less cylinder as standard, or you can add a conventional 6-pin or conventional 7-pin cylinder with the order. Keying is your call too: keyed different is standard, and keyed alike is available when you want a group of openings on one key. That last option is the one property managers and facility buyers want when standardizing a wing or a building on a single classroom key.

5) Will Corbin Russwin ED2200 series trim fit a 1-3/4 inch door, and what about a thicker one?

1-3/4 inches (44mm) is the standard door thickness for the ED2200/ED2400 hardware, which covers most commercial openings. Thicker doors are handled with a device option: 2 inches with the D200 option, or 2-1/4 inches with D214. Those have to be specified at order time, not adapted in the field. Minimum stile width is 4-1/2 inches (114mm), so this is wide stile hardware and will not go on a narrow stile aluminum storefront door.

6) Is the x555ET trim ADA compliant and Grade 1 for a school or healthcare corridor?

ANSI/BHMA A156.3 Grade 1, and the lever trims comply with the Americans with Disabilities Act. The device line it mounts to is UL listed panic and 3-hour fire exit hardware, NFPA 101 and NFPA 80 compliant, and California State Fire Marshal approved. Lever trim rather than a knob is what carries the ADA side of that, since a lever operates without grasping or twisting.

7) Is there another classroom lever exit trim besides the Corbin Russwin 555ET?

Two others cover classroom function. The Detex 08BN is a classroom S-lever exit device trim with a mortise cylinder for the Detex Value Series, in the BN Series. The Arrow SRX87 is a classroom trim with a Sierra lever and rose for the S1150/S1250/ED910/PEC910 Series. The Corbin Russwin 555ET is the classroom lever trim for ED2200/ED2400 Series devices. All three key the lever locked or unlocked, but each is built to its own manufacturer's device, so the choice follows the exit device already hung on the opening.

8) Classroom or storeroom trim - which one belongs on the door?

It depends on whether staff need to change the lever's state. The Corbin Russwin 555ET is classroom function: entrance by lever, and the key locks or unlocks the lever, so it can be left unlocked during the day. Storeroom trim keeps the lever locked at all times and the key retracts the latch for entry only. The Deltana DDS-36 is storeroom lever trim for the Exit Device 80, and the Deltana LTED60LST is storeroom lever trim for the Exit Device 60. Either way, egress from the inside is by the push bar.

9) What should be used instead of the 555ET on an opening that needs code entry rather than a key?

Two electronic trims cover that. The Dormakaba E-Plex E5010 is a push button electronic exit device lever trim with key override, Grade 1, fitting doors 1-3/8 inch to 2-1/4 inch thick. The BEST EXZ is an electronic keypad exit device trim with key override in the EZ Series. Both let a user enter a code at the door instead of carrying a key. The Corbin Russwin 555ET is mechanical classroom trim keyed with a conventional 6-pin or 7-pin cylinder, so it stays on a key system rather than a code.

10) Which exit trims look like a substitute for the 555ET but will not operate the latch?

The blank and pull trims. The Von Duprin 379L-BE is a blank escutcheon trim for 55 Series rim devices, the Sargent 802 is a blank plate trim with GTB design in the PE80 Series, and the Detex 03WS is a trim plate with a cylinder hole for 10/20/21/27 Series devices. None of them carries a lever that retracts the latch from the outside - they dress the door face, and the 03WS carries a cylinder for dogging or locking the device. The Corbin Russwin 555ET is lever trim with a classroom function that lets a user enter by turning the lever.

11) Which lever designs and finishes does the Corbin Russwin x555ET classroom trim come in?

Three lever designs: A5 Armstrong, N5 Newport, and PR5 Princeton. Each is offered across the same eleven finishes, so you can match the lever shape to what is already on the building and still land the finish. The finishes are 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 613E dark oxidized satin bronze equivalent, 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 fleet of doors already running 626, that is the one to hold to.

12) Will the x555ET lever hold up on a high traffic door where students pull on it?

The trim uses free wheeling levers, which is the vandal resistance feature that matters on a school door: when the lever is locked, it spins freely instead of transmitting force into the chassis, so someone hanging on it or forcing it down does not break the lock. Combined with the heavy duty cold-forged steel chassis and electroplated corrosion resistance behind it, this is a heavy duty commercial trim, not a light-commercial one.

13) What is the difference between classroom exit device trim and storeroom or passage trim?

It comes down to what the outside lever does. Classroom trim, like the x555ET, lets the key lock or unlock the outside lever, so staff can leave it unlocked all day and secure it with a turn of the key. Storeroom trim keeps the outside lever locked permanently and the key only retracts the latch for entry, which is what the Deltana DDS-36 and LTED60LST trims do. Passage trim, like the Deltana LTED80LP, never locks at all, and is for doors that only need free operation from both sides. Pick classroom when the same door needs to change state during the day.

14) Is there a keypad or keyless alternative to keyed classroom lever trim on an exit device?

If you want to stop issuing keys, there are electronic and mechanical trims that mount to exit devices instead. The Dormakaba E-Plex E5010 is a push button electronic lever trim with key override, Grade 1, covering 1-3/8 to 2-1/4 inch doors, which is a wider thickness range than the 1-3/4 inch standard on the Corbin Russwin trim. The BEST EXZ is an electronic keypad exit trim with key override for EZ Series devices. For a mechanical pushbutton with no batteries, the Lockey 285P panic trim handles 1 3/16 to 2 inch doors. All of them still need to match the device family already on the opening.

15) Do I need the lever trim at all, or will a pull work on my exit device door?

Only if the door has to be entered from the outside. A keyed classroom lever gives controlled entry; if the opening never needs outside entry, a blank plate covers the trim prep and forces the door to be exit-only, and the Sargent 802 blank plate or the Von Duprin 379L-BE blank escutcheon do that job on their respective device lines. Where you want key-only entry with a pull rather than a lever, the Sargent 814 PSB is a night latch pull. The lever is what you order when people are coming and going through the door regularly.

16) I have a pair of doors with an ED2200 rim device on each. Does the trim change anything about the mullion?

The trim does not affect the mullion decision. A rim device needs a strike to latch into, so a pair of doors running rim devices requires a removable mullion between them; a keyed removable mullion such as the Detex 90 Series is what lets you take it out to move wide loads through the opening. If you would rather not have a mullion in the way at all, the surface vertical rod version of the device latches at the head and threshold instead, using a 3/4 inch throw pullman latch at the top and a 5/8 inch throw deadbolt at the bottom. The classroom lever trim mounts either way.

17) Will the ED2200 latch into the strike prep already in my frame?

The rim device throws a stainless steel pullman-type latchbolt with a 3/4 inch (19mm) throw and a deadlocking auxiliary latch, and it comes with its own surface-mounted 3/8 inch roller strike with a positive locking plate and shims. Because the strike surface mounts rather than mortising into the frame, you are not matching an existing mortise strike prep. Projection off the door face is 3-1/4 inches (83mm) active and 2-3/4 inches (70mm) dogged, which is what to check against anything mounted nearby on the frame or wall.

18) Can I hold the door unlatched during the day with an ED2200 classroom setup?

Dogging handles that, not the trim. Standard on the panic devices is single-point 1/4-turn hex key dogging, which holds the push bar depressed so the door pushes open freely, and cylinder dogging or electric dogging can be specified instead. Worth knowing: dogging is only available on panic devices. Fire rated exit hardware cannot be dogged mechanically, so on a fire door you leave the classroom lever unlocked with the key instead.

19) Can this exit device be tied into an access control system with electric latch retraction?

Electrified options on the line include delayed egress, electric latch retraction, and electric dogging, so the device can be released from a card reader or a front desk. If you are retrofitting electric latch retraction onto an existing Corbin Russwin ED4000 Series rim device rather than buying a new one, the ACSI ED4200-W036 is a Grade 1 wide stile rim device with 24 volt AC/DC electric latch retraction built in. The classroom lever trim still gives you mechanical key entry when the power drops.

20) What is a simpler alternative if the door does not need to be keyed?

Drop to a passage or pull trim. The Deltana LTED80LP is passage function lever trim for the Exit Device 80, so the lever always retracts the latch with no cylinder involved. The Detex 0A is a straight pull trim with a blank escutcheon for the A/AN Series Value Series devices, and the Sargent 862 is an offset pull handle for exit devices, Grade 1, P800 Series. The Corbin Russwin 555ET is keyed classroom trim, where the key locks or unlocks the lever, so it is the wrong choice on an opening that is meant to stay free at all times.

21) Can a mechanical pushbutton panic trim replace the 555ET on a door with no key system?

The Lockey 115P and Lockey 285P are keyless mechanical panic trims with lever handles - the 115P is a heavy duty keyless passage lever panic trim supplied with the 1150 lock body, and both fit doors 1 3/16 inch to 2 inch thick. They operate on a mechanical code with no cylinder and no key. The Corbin Russwin 555ET is keyed classroom trim, so a facility that already runs a master key system and wants the lever controlled by that key stays with the 555ET, while a standalone door with no keying program is where the Lockey trims apply.

22) What is the difference between the 555ET and a nightlatch pull trim?

The Sargent 814 PSB is a nightlatch pull exit device trim, heavy duty, in the 80 Series - a nightlatch pull is key-retraction only, so the pull itself never opens the door and entry always takes a key. The Corbin Russwin 555ET is classroom lever trim where the lever gives entrance and the key locks or unlocks that lever, so it can be set free-entry for a class period and re-locked. Choose the nightlatch pull for a door that must stay locked to the outside at all times, and the 555ET where the lever state has to change through the day.

23) Which Grade 1 exit device trims compare with the Corbin Russwin 555ET?

The Corbin Russwin 555ET is ANSI/BHMA Grade 1 heavy duty trim. Grade 1 peers include the Von Duprin 379L-BE blank escutcheon for 55 Series rim devices, which is also heavy duty, the Sargent 802 blank plate in the PE80 Series, the Sargent 862 offset pull in the P800 Series, and the Dormakaba E-Plex E5010 electronic lever trim. Of those, only the E5010 gives a lever that operates the device from the outside; the rest are blank or pull trims. Grade level is the same across all of them, so the deciding factor is the function the opening needs.

24) What if the door needs the latch pulled back electrically instead of by lever?

That is a device change, not a trim change. The ACSI ED4200-W036 is a Grade 1 wide stile rim exit device with 24 volt AC/DC electric latch retraction built for the Corbin Russwin ED4000 Series, so the latch retracts on a signal and the door is free to push. The Corbin Russwin 555ET is mechanical classroom lever trim for ED2200/ED2400 Series devices, where entry comes from turning the lever with the key controlling whether it is locked. An access control system that unlocks on a card read points to the latch retraction device; a keyed opening points to the 555ET.

25) Which lever trim option covers an entry function rather than classroom?

The Deltana LTED80LS is entry function lever trim for the Exit Device 80. Entry function typically lets the lever be locked and unlocked at the door itself, while the Corbin Russwin 555ET is classroom function - entrance by lever, with the key locking or unlocking the lever, so the state is controlled from the key system rather than at the door. A school or institution that wants the lock state held by keyholders uses the classroom trim; a tenant space that wants control at the opening looks at the entry trim, sized to the Exit Device 80.

26) What handles a pair of doors that needs a keyed classroom lever on one leaf?

Add a mullion. The Detex 90KR is a 90 Series keyed removable mullion for rim exit devices, which gives each leaf of a pair a strike point for a rim device and can be pulled for wide loads. The Corbin Russwin 555ET is the keyed classroom lever trim for the active leaf, working with the ED2200/ED2400 Series device. The mullion is not an alternative to the trim - it is the additional piece a double-door opening needs alongside it.
