This device is built to be tight to your rack.

1. You can attach it coming out to the side of your rack using the front of the post holes with the 5/8-inch or 1-inch versions.

2. You can attach it to the inside of the rack as this device has top and bottom holes that are 6-inch on-center holes, standard for most racks.

RACK COMPATIBILITY

We pulled these specs straight from the rack manufacturers’ websites—so while we’ve done our homework, we can’t promise every single spec. This list doesn’t include every rack out there, it is not an exhaustive list, but if yours isn’t shown, don’t sweat it—chances are, the Infinity Arm will still fit like a glove… or at least like a well-worn lifting strap.

Quick rule of thumb:

If your uprights are 3x3” (or 75mm), 2x3”, or 2x2” (or 50mm)with standard hole spacing, you’re probably good to go. Our Infinity Arm will attach to 1-inch, 2-inch, 4-inch and 6-inch on-center hole spacing.

If your rack is some oddball size or thicker than 3x3”, it’s likely not compatible—unless you’re ready to get crafty with some shims, which we don’t supply or if you got a buddy with a 3D printer.

Also keep in mind—this compatibility list is for our Infinity Arm, so double-check your upright size before you hit “add to cart”—because size does matter.

This list doesn’t cover every rack on the planet—just the ones we’ve wrangled into the lineup so far, or been asked about. If yours isn’t listed, don’t panic. Odds are it’ll still play nice with the Infinity Arm… you’ll just need to check the specs and make sure your rack isn’t out here trying to be “special.”
