This thing ain’t goin’ nowhere without a blasting cap. Attaches to the ground, a wall, or any immovable surface you want to put it on. And stays put. The 5/8” hardened carbon alloy steel shackle lays flat when not in use, making it safe to walk or drive over. Comes with big honkin’ masonry bits and bolts for optional installation in driveway, garage, etc. 7.5”x1.7”, 6 lbs.
