Newbold's 6" Square HangTuff Target hangs down from 2X3s, 2x4s and 1x6s. The 6" Square HangTuff attaches easily with two wood screws, which are included. When hit, these targets flip around in all directions. For maximum movement, shoot .22-Cal. at the 6-inch HangTuff. The flexible strap is made of ElastiMAX™, the same self-sealing material as the target. Bullets pass through the polymer target and the strap. The 6" Square HangTuff Target attaches easily with wood staples when wood screws are not permitted.
