Newbold's 4" HangTuff Target hangs down from 2X3s, 2x4s and 1x6s. The 4" HangTuff attaches easily with two wood screws, which are included. When hit, this target flips around in all directions. For maximum movement, shoot .22-Cal. at the smaller 4" 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 4" HangTuff Target can easily attach with wood staples when wood screws are not permitted.
