Corbin Russwin A557ET 626 – Frequently Asked Questions

1) What does nightlatch function actually do on an exit device trim?

Nightlatch means the outside lever is always locked and does nothing on its own. You put the key in, the key retracts the latchbolt, and that is how you get in from outside. The key comes out only in the locked position. Push the device from inside and you always get out. If you want the lever to stay unlocked for a period, a nightlatch is not what you want.

2) Do I have to order a left hand or right hand version of this Corbin Russwin nightlatch trim?

No handing to specify. The 557ET trim is non-handed, so the same part goes on a left or right hand opening. Worth noting on Corbin Russwin exit devices generally, since lever trim and double cylinder configurations are the exception that do get handed on some series.

3) Does the Corbin Russwin 557ET nightlatch trim come with a cylinder?

Not by default. The standard configuration ships less cylinder, so you supply your own to match your keyway and system. If you want it with one, the trim can be ordered with a conventional 6-pin or conventional 7-pin cylinder. Keying is either keyed different, which is the standard, or keyed alike when you need a set of doors on one key.

4) What is the closest nightlatch trim to the Corbin Russwin 557ET if the exit device is a Sargent 80 Series?

The Sargent 814 PSB is a nightlatch pull trim built for the Sargent 80 Series and rated heavy duty. The functional difference is the grip: the Corbin Russwin 557ET is lever trim with a rose, while the 814 PSB is a pull. Both give entry by key at the trim, but the 557ET is device-matched to the ED2200/ED2400 Series, so the two are not interchangeable across device families - pick the trim that matches the device already on the door.

5) I need a classroom function lever trim instead of a nightlatch - what are my options?

The 557ET is nightlatch function: entrance by trim when the latch bolt is retracted by key, key removable only when locked. If the opening needs classroom function, the Arrow SRX87 is a classroom lever trim with rose for the S1150/S1250/ED910/PEC910 Series and fits a 1-3/4 inch door, and the Detex 08BN is a classroom S-lever trim with mortise cylinder for the Detex Value Series BN trim line. Both are device-family specific, so match the trim to the exit device on the door.

6) Is a blank escutcheon or blank plate trim a substitute for the 557ET nightlatch trim?

No. The Sargent 802 is a blank plate trim with GTB design for the PE80 Series, the Von Duprin 379L-BE is a blank escutcheon for 55 Series rim exit devices, and the Detex 0A is a straight pull trim with blank escutcheon for the Value Series. All three cover the outside of the door with no key function - they are exit-only trim. The Corbin Russwin 557ET is a keyed nightlatch lever trim, so it is the choice when someone needs to get back in through the door with a key.

7) I need every exit door in the building on one key. Can this trim be keyed alike?

Yes, keyed alike is an ordering option on the 557ET trim, which is how you get a whole run of exit doors opening on a single key. Order it that way at the outset, and specify the same cylinder pinning (6-pin or 7-pin) across all of them so the key bitting matches. The default if you say nothing is keyed different.

8) What lever designs and finishes does the Corbin Russwin 557ET trim come in?

Three lever designs: A5 Armstrong, N5 Newport, and PR5 Princeton. Each of the three is available in all eleven finishes, which run 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. If you are matching existing openings, pick the finish code off the back of the old trim rather than by eye, since 613 and 613E look close but are not the same.

9) Is this trim rated for a school or hospital corridor door, or is it light duty?

The 557ET is heavy duty commercial trim, ANSI/BHMA Grade 1, the top grade in that standard. That is the level normally specified for schools, healthcare corridors, and other high-traffic institutional openings. It is not a residential part.

10) Should I use a nightlatch lever trim or a classroom function trim on my exit door?

Depends who needs to get in and how often. A nightlatch like the 557ET keeps the outside lever dead at all times and grants entry only while the key is turned, which suits a back door or after-hours entrance where nobody should walk in without a key. A classroom function lets the key set the outside lever unlocked so people can enter freely until it is keyed back, better for a room that is open through the day. The Arrow SRX87 lever trim is a classroom function option, though it fits Arrow S1150/S1250/ED910/PEC910 devices, not Corbin Russwin ED2200/ED2400.

11) I do not want a lever on the outside of my exit door. What are the alternatives?

A pull trim rather than a lever. The Sargent 814 PSB is a heavy duty nightlatch pull trim for Sargent 80 Series devices, so you get the same key-retracts-the-latch behavior with a fixed pull instead of a handle. If you want nothing operable outside at all, a blank plate covers the prep, such as the Sargent 802 for PE80 Series or the Von Duprin 379L-BE blank escutcheon for 55 Series devices. All of those are tied to their own device families, so match the trim to the device brand on the door.

12) Can I get a code or keypad on the outside instead of managing keys for this exit door?

Not with the 557ET, which is a keyed nightlatch and needs a cylinder. For keyless entry on an exit device the options are electronic or mechanical push button trim. The Dormakaba E-Plex E5010 is a Grade 1 electronic push button exit trim with key override that covers 1-3/8 to 2-1/4 inch doors, and the BEST EXZ is an electronic keypad exit trim, also with key override. On the mechanical side, the Lockey 285P and 115P are keyless push button panic trims for doors 1-3/16 to 2 inches thick. Each is matched to its own device family.

13) What is the difference between the Corbin Russwin 557ET and the Detex 03WS trim plate with cylinder hole?

The Detex 03WS is an exit device trim plate with a cylinder hole for Detex 10, 20, 21 and 27 Series devices - a plate that accepts a cylinder, with no lever. The Corbin Russwin 557ET is a Grade 1 lever trim with rose and nightlatch function for ED2200/ED2400 devices. If the specification calls for a graspable lever on the outside, the 03WS does not satisfy it.

14) Is there a keyless lever panic trim I can use instead of the 557ET so I do not have to key the door?

The Lockey 115P is a heavy duty keyless passage lever panic trim with a 1150 lock body, and the Lockey 285P is a keyless mechanical panic trim with lever handle; both fit doors 1 3/16 to 2 inches thick. Those are mechanical pushbutton trims that need no cylinder. The Corbin Russwin 557ET is a keyed nightlatch lever trim for ED2200/ED2400 devices and takes a conventional 6-pin or 7-pin cylinder, so it is the one to specify when the door has to work on the building keyway.

15) Is a removable mullion an alternative to buying nightlatch trim for a pair of doors?

They solve different problems. The Detex 90 Series keyed removable mullion is a vertical post for a pair of doors carrying rim exit devices, allowing both leaves to take rim hardware. The Corbin Russwin 557ET is the outside trim that provides key entry at the door itself. A mullion does not give anyone a way in from the outside, so an opening that needs both a pair with rim devices and key entry needs both parts.

16) What do I use if the door needs electric latch retraction rather than key entry through the trim?

The ACSI ED4200-W036 is a Grade 1 wide stile rim exit device with 24 volt AC/DC electric latch retraction built for Corbin Russwin ED4000 Series. That is a complete device that retracts the latch electrically from an access control signal. The Corbin Russwin 557ET is trim only, nightlatch function, keyed, and mounts to an ED2200 or ED2400 device - it is the mechanical route to entry on the same kind of opening.

17) If I want the outside lever always free instead of key-only entry, what trim should I order?

Passage trim. The Deltana LTED80LP is passage function lever trim for the Exit Device 80, and the Lockey 115P is a keyless passage lever panic trim. The Corbin Russwin 557ET is nightlatch: the key retracts the latch bolt and the key is removable only when locked, so the outside lever is not free-turning entry hardware. Choose passage where the door is unsecured during business hours and nightlatch where it must stay locked to the outside.

18) Is a nightlatch trim ADA compliant for a lever handle?

Lever trim is what gets you there. Corbin Russwin exit device lever trims and pulls are stated ADA compliant, and the 557ET is a lever, so an Armstrong, Newport, or Princeton lever operates without tight grasping or wrist twisting. Note that on a nightlatch the outside lever is only live while the key is turned, so where the code official is looking at free entry from the outside, a nightlatch may not be the function they want.

19) Can I order a pull handle instead of lever trim for the outside of an exit device?

Yes, if the door does not need key entry. The Sargent 862 is a Grade 1 offset pull handle for exit devices in the P800 Series, and the Detex 0A is a straight pull trim with blank escutcheon. Neither is keyed. The Corbin Russwin 557ET is a Grade 1 keyed lever trim, and its lever is ADA-relevant graspable hardware where a fixed pull is not.

20) How does entry function lever trim differ from the 557ET nightlatch on an exit device?

The Deltana LTED80LS is entry function lever trim for the Exit Device 80. Entry function is typically locked or unlocked at the trim and then operated by lever. The Corbin Russwin 557ET is nightlatch, Grade 1, heavy duty, non-handed, where entry is by key retracting the latch bolt each time. On a back-of-house or service door that must never be left unlocked, nightlatch is the tighter function.
