Over-Under Mount The Over-Under Mount lets you run two Beyond Power VOLTRA I units simultaneously on a single rack position by stacking one directly above the other. Its slim, low-profile design fits neatly into tight or narrow spaces where other mounts simply won’t. When installed, the VOLTRA I is oriented perpendicular/horizontal to the rack upright or crossmember — delivering maximum vertical efficiency while saving valuable rack height. Note: If you prefer the VOLTRA I oriented parallel / in-line with the upright or crossmember, we also offer the Side-by-Side Mount. This secure single-pin mount provides a stable connection with quick and easy height adjustments during your workout. Built with the same precision fit and rock-solid construction as all Voltra Mounts, it eliminates the need for extra equipment or complicated setups while making your entire VOLTRA I system far easier to move and reconfigure between locations. What’s Included: Chafe pad shims for a tighter fit and reduced movement Allen wrench for adjustments Proudly made in the USA for serious athletes who demand reliable fit and performance. Note: The push pin and DIY Docks shown in product images are not included.
