12 Gauge Perimeter Trip Alarm W/ .22Cal Adapter Kit*

The Fith OPS Perimeter Trip Alarm is made of 6061 Aluminum, this unit utilizes a spring loaded firing mechanism and a trip trigger. When the trigger is disturbed while loaded with a 12 gauge flash bang or .22 adapter, the unit will discharge. This device is compatible with 12 gauge power flash bangs, .22Cal CCI Power Loads, flares, and pepper gas depending on situation and requirement.

This new .22 adapter only works in our new, updated 2022 FithOps 12 gauge perimeter trip alarm, the one with 2 curved sides and 2 straight sides. It does not work in the older models (the square bodies). We apologize for this inconvenience.

.22 power loads are rim fires, that is why the hole on the top is not centered, it will not work if the fire pin hits directly on the power loads. This is not an error or machining issue. It is meant to be an offset center.

If removal of the spent powerload/ramset is difficult we recommend using pliers to pull it out the rest of the way.

22 caliber trip alarm.

Absolutely fantastic, but I think the 12 gauge is great as well. Both products 100%.

We ordered several to resell and are very happy to see the quality and reliability are as expected. If you’re considering purchasing, this is the one you want. You won’t be disappointed.

Great product

I have a big property which backs up to a wash. A few adventuresome people have walked on my property back by our gate to the wash. I decided to place a Perimeter Camp safe trip alarm on the wash great and hopefully I never hear it go off!!
