Doubler Plate – Voltra 2:1 Bolt-On Resistance Doubler for Existing Mounts

The Doubler Plate is the smartest, most affordable way to upgrade any existing VOLTRA I mount into a true 2:1 system.

This precision-cut plate bolts directly onto your current mounts — including the Beyond Power Travel Platform, Darko Quick Mount, and many other compatible mounts. Once installed, it creates a clean block-and-tackle setup that delivers true 2:1 mechanical advantage, instantly doubling the felt resistance of your VOLTRA I (up to 400 lbs) with zero extra footprint.

No need to buy entirely new specialty rack mounts. Just bolt on the Plate Doubler and double your cable machine power.

Replacement hardware is included with your purchase. Proper installation is the responsibility of the purchaser.

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

IMPORTANT NOTE: 

The Doubler Plate requires a flat mating surface to be securely attached to any mount. If the surface is not flat, or if protrusions such as screws, nuts, or other hardware prevent the Plate Doubler from sitting flush, it must not be installed. See image gallery for specific dimensions and follow the install guide for your plate type above.

Additionally, the Magnetic Plate installed on your original mount (in the center of the DIY Dock) must be removed and transferred to the Plate Doubler. The adhesive pad used to attach the Magnetic Plate will require cleaning and reuse.
