How upright size works

Our mount designs stay the same. Fit for other upright sizes comes from sized chafe pads when you pick that option. Pick the size that matches your rack so the pads ship ready to fit.

For fine-tune on a standard 3×3, see shim kit installation.

Upright Size Width × Depth: top-down tubing cross-section. Depth is front-to-back of the tube, not rack height.

Cross 2:1 Doubler 

The Cross 2:1 Doubler Mount securely attaches your Beyond Power VOLTRA I any standard 3x3 rack while providing a dedicated pulley arm for a true block-and-tackle setup. This delivers real 2:1 mechanical advantage, doubling the felt resistance of your VOLTRA I — up to 400 lbs.

Its slim, low-profile design allows it to fit neatly into tight or narrow spaces. When installed, the VOLTRA I is oriented perpendicular to the rack upright or crossmember.

Note: If you prefer the VOLTRA I oriented parallel / in-line with the upright, we also offer the Inline 2:1 Doubler Mount.

This single-pin mount provides a secure, stable connection with quick and easy height adjustments during your workout.

What’s Included:

  • Chafe pad shims for a tighter fit and reduced movement
  • Allen wrench for adjustments

United States flag Proudly made in the USA for serious athletes who demand reliable, space-saving performance.

Note: Push pin, DIY Dock and carabiner shown in product images are not included.
