Corbin Russwin K157ET 626 6P – Frequently Asked Questions

1) Will the Corbin Russwin K157ET trim fit my ED2200 or ED2400 exit device?
The K157ET is built specifically for the Corbin Russwin ED2200 and ED2400 Series exit devices and comes with the rose. It is not a universal trim, so it will not mount to another maker's device or to a Corbin Russwin device outside those two series. If your device is an ED2200 or ED2400, this is the matching key-only trim.
2) What does key only trim actually do on a classroom exit device?
Key only means there is no lever or knob on the outside, just a cylinder in a rose. From outside, the key retracts the latch to let you in; there is no handle to grab if the door is locked. Inside, the push bar always allows free egress. If you want teachers or staff to enter without a key when the door is left unlocked, you need a lever trim instead, not this one.
3) Is the K157ET exit device trim handed, and do I need to know which way my door swings?
Non-handed. The K157ET mounts the same on a left- or right-hand door, so one part number covers every opening in the building and you can stock one spare rather than two. Handing only becomes a concern on lever trims and double cylinder devices in this family.
4) What door thickness does the Corbin Russwin K157ET trim work on?
Standard is 1-3/4 inch (44mm), which is the normal commercial door. Thicker doors are handled with the optional 2 inch (D200) or 2-1/4 inch (D214) door thickness options, and that choice changes the cylinder tailpiece length, so measure the leaf before you order rather than after the device is on the door.
5) Which cylinder do I order with the K157ET, and can I use my building's existing interchangeable core?
Six cylinder configurations are offered: conventional 6-pin (6P) or 7-pin (7P), large format interchangeable core 6-pin (C6) or 7-pin (C7), and the same LFIC prepped less core (CL6 and CL7). If your facility already keys everything on large format cores, order CL6 or CL7 and drop your own core in, which keeps the opening on your existing master key system without sending the pinning out.
6) What is the closest equivalent to the Corbin Russwin K157ET classroom exit device trim from another manufacturer?
The Arrow SRX87 is the nearest match in function. It is exit device trim in classroom function with a Sierra lever and rose, fitting the S1150/S1250/ED910/PEC910 Series, and lists a 1-3/4 inch door thickness. The Corbin Russwin K157ET is also classroom function with a rose, but it is built for ED2200/ED2400 Series devices, so the two are not interchangeable on the same device - pick the trim that matches the exit device already on the door.
7) Is there a classroom exit device trim with a lever and a mortise cylinder instead of the Corbin Russwin K157ET?
The Detex 08BN is a classroom S-lever exit device trim that takes a mortise cylinder, built for Detex Value Series devices in the BN Series. The Corbin Russwin K157ET is also classroom function but is ordered with its own cylinder options - 6-pin or 7-pin conventional, or LFIC 6-pin or 7-pin, including less-core versions for a facility that stamps its own cores. Choose by which exit device is on the door and which cylinder format your keyway uses.
8) What is the difference between the Corbin Russwin K157ET and a storeroom trim like the Deltana DDS-36?
The Deltana DDS-36 is lever trim for an 80 exit device in storeroom function, where the outside lever stays locked and a key retracts the latch for each entry. The Corbin Russwin K157ET is classroom function: entrance by knob or lever, with the key locking or unlocking the knob or lever, so a teacher can leave the opening unlocked for a period and re-secure it with the same key. The Deltana LTED60LST is the same storeroom idea for a 60 exit device.
9) Are blank plate trims like the Sargent 802 or Von Duprin 379L-BE a substitute for the Corbin Russwin K157ET?
No. The Sargent 802 is a Grade 1 blank plate trim in the PE80 Series and the Von Duprin 379L-BE is a Grade 1 blank escutcheon for 55 Series rim devices - both cover the outside of the door with no way in, for exit-only openings. The Corbin Russwin K157ET is keyed classroom trim that lets a key lock or unlock the knob or lever from outside. If anyone needs to get back in through that door, a blank plate is the wrong part.
10) Can I get several of these keyed alike so one key opens all my classroom doors?
Yes. Keying is a required choice at order time: KD keyed different is standard, and KA keyed alike is selected when a group of trims needs to run on one key. Order the whole group as KA in a single order so they land in the same key set.
11) Is this trim heavy duty enough for a school corridor or a high traffic entrance?
It's an ANSI/BHMA A156.3 Grade 1 commercial product, rated heavy duty, which is the top grade for this class of hardware and the level normally specified for schools, healthcare and government buildings. Key-only trim also gives you nothing on the outside for someone to hang on or pry, which is part of why it gets used on abuse-prone openings.
12) What's the difference between key only trim and a blank plate on an exit device?
Key only trim carries a cylinder, so the door can be unlocked and entered from outside with a key. A blank plate has no cylinder and no handle at all, which makes the opening exit-only with no outside access whatsoever. If you want an exit-only door, the Sargent 802 blank plate with GTB design or the Von Duprin 379L-BE blank escutcheon for 55 Series rim devices does that job. If staff need to get back in with a key, key only trim is the right call.
13) Does the K157ET trim come with the exit device, or do I have to buy the device separately?
Trim only. The K157ET is the outside cylinder and rose assembly that mounts to an ED2200 or ED2400 exit device, and the device itself, the strike and the mortise cylinder are separate lines. If you are replacing worn or vandalized outside trim on a device that still works, this is all you need; if the door is bare, you're ordering the device too.
14) Which exit device trim should I order if I want a keypad on the outside instead of the Corbin Russwin K157ET's key?
For code entry, the BEST EXZ EZ Series electronic keypad exit device trim has key override, and the Dormakaba E-Plex E5010 is Grade 1 push button lever trim with key override that covers a 1-3/8 inch to 2-1/4 inch door thickness range. The Corbin Russwin K157ET is a keyed mechanical trim, Grade 1, with no credential entry - it is the right pick when the facility keys everything to one system rather than managing codes.
15) Is a pull trim like the Sargent 814 PSB nightlatch the same thing as the Corbin Russwin K157ET?
They solve different openings. The Sargent 814 PSB is a heavy duty nightlatch pull trim in the 80 Series, where the key retracts the latch for entry and the pull is the only handle. The Corbin Russwin K157ET is heavy duty classroom trim with a lever, where the key locks or unlocks the lever so the door can be left in an unlocked state. The Sargent 862 offset pull is a Grade 1 pull for exit devices with no keyed entry at all.
16) Can I use a keyless mechanical trim like the Lockey 285P in place of the Corbin Russwin K157ET on a classroom door?
The Lockey 285P is a keyless mechanical panic trim with a lever, covering a 1 3/16 inch to 2 inch door thickness range, and the Lockey 115P is a keyless passage lever panic trim over the same range with a 1150 lock body. Neither uses a key. The Corbin Russwin K157ET is keyed classroom trim and accepts conventional 6-pin and 7-pin or LFIC cylinders, which is what a school needs when the door has to fall under the building master key system.
17) I need the outside of the door to release electrically rather than by key - what takes the place of the Corbin Russwin K157ET?
That is a device-side change, not a trim change. The ACSI ED4200-W036 is a Grade 1 wide stile rim exit device for the Corbin Russwin ED4000 Series with 24 volt AC/DC electric latch retraction, which unlatches the opening from an access control signal. The Corbin Russwin K157ET is mechanical keyed classroom trim for ED2200/ED2400 devices, so an electrified opening is specified at the device, with the trim chosen to match.
18) Is entry function trim the same as the classroom function on the Corbin Russwin K157ET?
They are close but not the same. The Deltana LTED80LS is lever trim for an 80 exit device in entry function. The Corbin Russwin K157ET is classroom function - entrance by knob or lever, with the key locking or unlocking the knob or lever - which is specified where the lock state must only ever change with a key, not from inside the room. On school and institutional openings that distinction is usually written into the door schedule.
19) What finishes does the Corbin Russwin K157ET come in for matching the rest of my door hardware?
Eleven finishes: 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. 626 satin chrome is the usual institutional standard, so if the other openings in a school or office already look like brushed silver, that is almost certainly the match.
20) A trim plate with just a cylinder hole was quoted instead of the Corbin Russwin K157ET - what is the difference?
The Detex 03WS is a WS Series exit device trim plate with a cylinder hole for 10/20/21/27 Series devices: the cylinder mounts through the plate to operate the device, with no handle to grip. The Corbin Russwin K157ET is key only trim with a rose in classroom function, where the key locks or unlocks the knob or lever. If the quote was written for a plate and you expected a graspable handle, those are two different parts.
21) Which trim matches an existing finish if I am standardizing exit devices across a building?
The Corbin Russwin K157ET is offered in 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, and it is non-handed, so one part number covers left and right openings. Where a door carries a different device family, the Arrow SRX87 provides the same classroom function on S1150/S1250/ED910/PEC910 Series devices.
22) Do I need a mullion in addition to the Corbin Russwin K157ET on a pair of doors?
On a pair of doors with rim devices, the Detex 90KR is a 90 Series keyed removable mullion that gives each leaf a strike and can be taken out for wide loads. It is not a substitute for trim - the Corbin Russwin K157ET is the keyed classroom trim that operates the ED2200/ED2400 device from outside, and a mullion opening needs both parts specified.
23) What is the simpler option if the door only needs a pull and no key function at all?
The Detex A/AN Series straight pull trim with blank escutcheon suits Value Series exit devices where the outside just needs something to grip, and the Sargent 862 is a Grade 1 offset pull handle for exit devices. Both leave the opening exit-only from the inside device. The Corbin Russwin K157ET adds keyed classroom control, which is what you order when the outside has to be locked and unlocked.
