Fith Ops Adapters & Trip Line
USA INVENTED & MADE: Fith Ops is the original inventor of the perimeter trip alarm. We came up with the look, feel and design. Any other devices you see that have our exact look are counterfeit products. We are the original company operating in Idaho.
BUILT TO LAST: We put quality above all else. We vigorously test our trip alarms on the hardest primers, so we know it will work with any type of blank you have. Our springs are very high quality and will not hold a memory, even after years of use (the same can’t be said with the counterfeit versions).
LOW-TECH: Our trip alarms are fully off-grid. You can use it as a sound alarm system to keep intruders or dangerous animals away from your home, garden, campsite, etc. without having to rely on wifi or power.
COMPACT: Being able to fit multiple in the palm of your hand, the compact size is perfect to take along while camping, hiking, hunting, etc.
FLEXIBILITY: It works with non-lethal 12G blanks, but will also work with 209 primers, .22s, or 308 blanks with the corresponding adapters. Additionally we make a digital adapter, for cases where you are not allowed to have blanks in your area.
NOTICES: Do not use live ammo. It is designed to work only with non-lethal blanks. Keep away from flammable objects. Always mount low to the ground and always point down. If you use in rain or snow, you must lube the spring with gun oil or some other type of waterproof salient. If not, the spring will rust.
