Six Adams Rite strikes, one family, and one question first

The UltraLine electric strike from Adams Rite is built for a storefront door that fights back. Wind pushes on it, the closer pushes on it, somebody leans on it, and an ordinary strike will not release. The UltraLine is preload-capable, which means it releases with the door pressed against the frame. That part is the same on every model in the family.

What changes from model to model is what the strike mounts into and what latch it catches. Get that wrong and you are not choosing between good and better. You are ordering a part that cannot work on your frame. So the first question is never "which one is best." It is "what is the jamb made of, and what is the lock on the door?"

The family at a glance

Model	Listed for	Latch it works with	Finish in the listing
7400-313	Radius jambs, per the listing title	Adams Rite MS deadlatches and deadlocks	Dark Bronze Anodized
7410-313	Wood jambs	Adams Rite MS deadlatches and deadlocks	Dark Bronze Anodized
7411-313	Wood jambs	Listed with the 7410/7411 pair	Dark Bronze Anodized
7430-313	Aluminum jambs	Adams Rite MS deadlatches and deadlocks	Dark Bronze Anodized
7440-313	Steel and wood jambs and doors	Adams Rite MS deadlatches and deadlocks	Dark Bronze Anodized
74R1-121	Rim type exit devices	3/4 in. latchbolt	Dark Bronze Powder Coat
74R2-130	Narrow stile rim exit devices	1/2 in. latchbolt	Clear Anodized

All of them list 12/24VDC and fail secure as supplied. The 7400 through 7440 are listed as field-convertible between fail safe and fail secure. That is the strike, not the whole door, so confirm the fail mode your lock and your code need before you wire it.

Step one: read the jamb, not the door

On an aluminum storefront the jamb is the narrow tube the door closes against. That is the 7430 case: aluminum jambs. It is the one most storefront work lands on, and it is the reason the family exists.

A hollow metal frame or a wood frame is a different job. The 7440 is the model listed for steel and wood jambs and doors. The 7410 and 7411 are listed for wood jambs. Both pairs of listings are plain about it: the strike is shaped for the frame it goes into.

The 7400 is the one to slow down on. Its listing title says radius jambs, while the web address on the same product page says square jambs. I will not settle that from my chair. The catalog listing and the page address disagree, so before you order a 7400, confirm the jamb profile against the Adams Rite spec sheet or send us a photo. This is the same advice as in our write-up on the 7400 and storefront preload. Guessing a jamb profile is an expensive way to find out.

Step two: what is the lock?

Five of the models list the Adams Rite MS deadlatch and deadlock family. If your door has an Adams Rite MS deadlatch or deadlock, the 7400 through 7440 are the strikes listed for it. If the storefront door is a different lock, stop and identify it first. Our piece on the 4510 deadlatch that will not latch covers the lock side of that door, and a deadlatch that does not catch will fail any strike you hang on it.

The 74R1 and 74R2 are a different animal. These are for rim exit devices, not MS locks. The listing splits them by latchbolt: the 74R1 for a 3/4 in. latchbolt, and the 74R2 for a 1/2 in. latchbolt on a narrow stile rim device. Count the latchbolt projection on your device before you pick. A device with a 1/2 in. bolt in a 3/4 in. strike is a rattling door, and a device with a 3/4 in. bolt in a 1/2 in. strike may not engage at all. The listing for the 74R2 also shows a Pullman latchbolt in its mount type. Read that as the latch style it is made to catch.

The 7410 and 7411: what the listing does not say

These two are listed on separate pages with nearly identical text. Both say wood jambs, both are dark bronze, both name the same 7410/7411 pair. The listing does not state what separates a 7410 from a 7411, and I will not guess. If you already have a 7410 on a door, order a 7410 for the next one. If you are choosing fresh, ask us before you buy, and we will check the part number against the Adams Rite sheet.

Depth, finish and the small stuff

1. Frame depth. The 7400 through 7440 listings mention lip extension kits, LEK7400, for non-standard frame depths. If your frame is deeper or shallower than standard, that kit is the part to look at, not a different strike.
2. Finish. Most of these are listed in dark bronze anodized, finish 313. The 74R1 is listed in a dark bronze powder coat, and the 74R2 in clear anodized. Match the finish to the frame. Do not treat it as an afterthought on a bright aluminum door.
3. Power. They list 12/24VDC. Check the supply you actually have. Our write-up on dirty power and strikes is worth a read if the supply is shared.
4. Verify the part number. The listings say images show the series, not the exact finish or handing. The part number is what counts.

When a different part is the right answer

If the door is not an aluminum storefront at all, the UltraLine may be the wrong family. A fire-rated door wants a fire-rated strike, and the UltraLine listings call themselves non fire rated. Our article on a fire-rated preload strike is the better starting point for that opening.
