THROOM HANGTUFF Targets hang down from 2X3s, 2x4s and 1x6s and attach easily with two wood screws, which are included. When hit, this THROOM Target flips around in all directions. For maximum movement, shoot .22-cal. at the smaller 2, 3, 4 & 6-inch HANGTUFF. The 8 inch HANGTUFF targets move more when hit with larger .38s, 40s & .45s. The flexible strap is made of SHOOT-THROO, the same self-healing material as the target. The HANGTUFF Target can also easier attach with wood staples when wood screws are not permitted. Bullets pass through the polymer target and the strap.
