These 25 bolt-on rock climbing holds by Rocky Mountain Climbing Gear are a durable, weatherproof set of mixed-size grips—hand-cast in the USA from recycled materials for indoor or outdoor climbing walls.

Build or upgrade a garage gym, home bouldering wall, school climbing structure, or outdoor training feature with a complete set of large-profile holds that give confident purchase and realistic texture. Each piece is pre-drilled for standard 3/8" bolts and designed to mount on 3/4" plywood; hardware is not included so you can choose t-nuts and bolts to match your wall system.

How do these holds mount to a climbing wall?

The holds are bolt-on style with a pre-drilled center hole sized for 3/8" bolts and compatible with standard t-nuts installed into 3/4" plywood. Choose appropriate grade hardware for indoor vs. outdoor use and ensure t-nuts are installed flush for secure seating.
