Atomik's Dry Tooling Holds come in 3 separate sections. First is our resin version that is 4 harder than the industry's standard resin. They mimic outdoor rock and do wear down with use. Second, our indoor climbing gym alternative, The Atomahawk, (patent pending) which is a dry tooling / ice climbing training device. It is a fantastic device that pairs with our rock climbing wall holds and hones your outdoor ice climbing and dry tooling skills while in the convenience of your home wall or commercial gym. Third are our Dry Ice Tools / Furnace Industries specific products.
