12-Gauge Blank Perimeter Trip Alarm — Olive Green

I like simple things that don't need batteries. This is a mechanical early-warning device: run a tripwire across a driveway or a camp approach, and when something pulls it, a 12-gauge blank goes off loud enough to hear from anywhere on the property.

What it is

An aluminum trip alarm that chambers one standard 12-gauge blank. Blanks are not included; any sporting goods store carries them.

• Fully mechanical, reusable: reset it, reload it
• Multiple tripwire points for up to 360-degree coverage from one unit
• Mounts to trees, posts, fences, or gate frames with screw holes or zip ties
• Aluminum alloy, olive green
• About 3.7 x 1.3 x 0.9 in, 5.2 oz
• Includes 1 alarm and 1 pull loop

Who ships it

Ships direct from the supplier's warehouse with tracking. Allow up to 2 weeks for delivery.

Read this first: 12-gauge blanks only. Never load live ammunition or anything else. Treat a loaded unit like a firearm, keep it away from children, and check your local regulations.
