When You Should Not Use the Wrong Sized Attachments rack tubing adaptersįor fitting 3×3 attachments onto 2×3 tubing, or 2×3 attachments onto 2×2 tubing, an Etsy seller is making these adapters to fill the void in the bracket. The tubes are fabricated to an outside diameter spec. Lastly, the steel gauge (wall thickness) of rack tubing does not factor into compatibility. Some don’t have enough pressure put on them to be a safety issue, like a battle rope anchor, but it could still rattle. Some attachments work well enough even if they’re loose. This can be less bad than the wrong peg size, because you can glue shims ( UHMW plastic or wood) to the inside of the attachment’s bracket to make it fit. Similarly, attachment brackets can fit onto slightly smaller tubing than what they were designed for. When Slightly Wrong Sized Attachments are OkĪn attachment can fit in a larger hole than it’s made for, but it will be able to wiggle and maybe tip down a little, depending on the snugness of the bracket that goes over the tubing. Some racks have Westside spacing, which is 1″ spacing at a certain height range for setting bench press safety bars just right, and otherwise 2″ spacing above and below that. This is only applicable for attachments that use 2 holes, the second using a locking pin.Ģ″ spacing is becoming the standard. The hole spacing in the uprights, ie: the distance between holes on center, as above. Going by the peg diameter is more consistent across brands than the hole size that is cut somewhat larger than the peg. The hardware/peg diameter that fits into the holes in the uprights, as above.

The tubing size of the uprights, as above, typically one of: 2″x2″, 2″x3″, or 3″x3″. Rear Rack Extension and Foot Stabilizer Fit.When You Should Not Use the Wrong Sized Attachments.When Slightly Wrong Sized Attachments are Ok.
