Targeted Strength. Minimal Compensation. Maximum Transfer.

The Grippūl Two is the refined evolution of our original portable grip-strength system. Engineered to isolate finger flexor loading without the influence of the wall, it’s designed for climbers, therapists, and coaches seeking measurable adaptation through biomechanically sound training. By removing the wall, the Grippūl Two helps eliminate compensatory movement at the shoulder, scapula, elbow, and wrist—common in traditional hangboard or climbing-based protocols. What you’re left with is pure finger flexor loading, grounded in research and applicable to real-world climbing.

The updated frame is constructed from heat-cast aluminum, making it lighter, stronger, and more ergonomic than the original model. A powder-coated surface adds subtle texture, providing ideal friction against climbing holds during loaded reps. Around the rim are six evenly spaced carabiner holes, allowing for seamless attachment to cable machines, loading pins, resistance bands, or any portable weight source. You can train anywhere—gym, clinic, or home.

Three 5/16” threaded inserts allow for adjustable mounting angles, enabling specific loading of the DIP and PIP joints through open-hand or half-crimp positions. These threaded points also accommodate pinch holds, so you can challenge the thumb’s opposition and control under load. Unlike traditional boards, which often bias the MCP joint and wrist flexors, the Grippūl Two brings attention back to the tendons and pulleys that matter most in high-force climbing scenarios.

Each unit includes our original 20mm Quad Crimp—textured with a “woodgrain” finish for added tactile control—making it ideal for max isometric efforts (e.g., 10-second holds with full recovery). The tool is equally suited for rehab, strength diagnostics, return-to-play testing, or use in structured protocols like the BFL Combine, where athlete profiles are developed using force-based metrics.

Whether you’re training max finger strength, reducing injury risk, or building climbing-specific capacity, the Grippūl Two offers a portable, systemized approach to hand strength training. It’s more than a tool—it’s a platform for intelligent progression.
