The rest of the 3080E part number

The Adams Rite 3080E electrified entry trim has one part number layout, and once you can read it you can order without a phone call. The exit device code, the fourth block, is its own question, and my companion article covers the 31, 33, 34, 36 and 37 codes. This one is about everything else: the lever shape, the handing, the voltage and the finish.

The catalog breaks 3080E-01-7-31-30 US3 down like this: series 3080E, handle 01 (curve lever), handing 7 (right hand reverse), cylinder and exit 31 (with cylinder hole, SVR exit device), voltage and features 30 (12 VDC, fail-secure), finish US3. Work from left to right.

Handle: 01, 02, 03

The second block picks the lever shape:

• 01: curve lever. See 3080E-01-7-31-30 US3 for a right hand reverse example.
• 02: round lever. See 3080E-02-0-31-30 US3.
• 03: square lever. See 3080E-03-0-31-30 US3.

The three are priced the same on our site in the same finish, so this choice is about looks and hand feel. Match what is already on the building. If the other doors in the corridor have square levers, a curve lever on one opening will read as a mismatch from across the lobby. Nobody has ever called to complain that a lever was too consistent.

Handing: 0, 7, 8

Most of the listings are handing 0, non-handed. A non-handed trim goes on a left or right hand door. That is the one to default to.

The catalog also carries 7 (right hand reverse) and 8 (left hand reverse). Handing 8 shows up in our listing for 3080E-02-8-9U-50 US32. I do not have a drawing that shows why a given door needs a reverse trim, and I will not make one up. If your existing trim has a handing marked on it, copy that number. When you are not sure, send us a photo of the door from the pull side and we will tell you which one it needs.

Voltage: 30 or 50

The fifth block is the one that bites people later. 30 is 12 VDC, fail-secure. 50 is 24 VDC, fail-secure. See 3080E-01-0-31-50 US3 for the 24 V curve lever.

Treat the voltage you order as the voltage you wire. The catalog gives one voltage per listing, and I have no instruction in front of me for switching one over in the field. Before you buy, look at what already powers the opening. On a retrofit, the existing supply decides it. A door with a 24 V access control supply wants a 50. A door fed by a 12 V supply wants a 30. Mixing them means a new supply or a trim that never energizes right.

On a new job, run the voltage drop for your own wire gauge and length before you choose. I do not have the trim's current draw in front of me, so I will not quote it. Pull it from the manufacturer data sheet and size the supply with margin. Our guide to the Securitron GL1 walks through the same fail-safe versus fail-secure thinking on a different lock.

Finish: US3 and US32

The finish repeats at the end of the number. Our catalog names US3 as bright brass on these trims and US32 as bright stainless. Read the finish off the product name, not off the code alone. On commercial hardware the same code can mean different things between manufacturers, and the product name settles it.

A worked example

Say the storefront has an exit device we already matched to code 31. The door takes a non-handed trim, the other doors have curve levers, the access control supply is 24 volts, and you want bright stainless.

1. Series: 3080E.
2. Handle: 01, curve.
3. Handing: 0 unless the existing trim is marked otherwise.
4. Exit code: 31.
5. Voltage: 50 for 24 VDC fail-secure.
6. Finish: US32 for bright stainless.

Put it together and you have 3080E-01-0-31-50 US32. That number is an example I built from the rules above. Check that the exact combination is on our site before you rely on it. The listings are individual SKUs, and I will not claim every possible combination exists.

Before you order: the four-line checklist

When a customer calls about a 3080E, these are the four things I ask, in this order, and they settle the part number nine times out of ten:

1. What exit device is on the door, and does the old trim have a cylinder?
2. What shape are the levers on the neighboring doors?
3. What voltage is on the supply that feeds this opening?
4. Is there a handing marked on the old trim?

If you can answer those from the door in front of you, you can build the number yourself and check it against the listing. If you cannot, a photo of the pull side and the exit device label is enough for us to do it.

Testing after the install

The trim energizes to free the lever. Test it with the exit device latched and the door closed, first without power, then with power. Without power, the lever should be locked and, if you ordered a cylinder hole, the key should retract the latch. With power, the lever should turn freely. If the lever feels rough in the powered state, check door alignment before you blame the trim. A door that sags into the frame loads the latch, and the trim ends up fighting it. For the strike side of that problem, our guide to the Adams Rite 7400 and preload covers the same failure.

Common questions

What is the difference between the 3080E 12V and 24V trims?

The voltage code. 30 in the part number is 12 VDC fail-secure, and 50 is 24 VDC fail-secure. Choose the one that matches the supply on the opening.

Which lever styles does the 3080E come in?

Curve (01), round (02) and square (03).

What does handing 0 mean on a 3080E?

Non-handed. The trim fits a left or right hand door. Handing 7 is right hand reverse and 8 is left hand reverse.

Is the 3080E fail-safe?

The listings we carry are fail-secure. The lever stays locked when power is off.
