The Keystone v2 brings a new challenge to lock-and-key obstacles with improved design and versatility. Upgraded from the original, it now features a backer board and includes scaffolding clamps for secure mounting. Attach it vertically to a pipe with the triangular opening at the bottom to ensure the keys lock in place, or suspend it with straps for an extra challenge. The Key Handle offers a beginner-friendly grip suitable for all skill levels, while the Key Peg—featuring a small, knobby pommel—demands precision and control for a more advanced test of grip strength. For added versatility, you can hang the Keystone and each Key individually, transforming them into swinging obstacles. Nylon Straps are sold separately.
