You get a hold of a great power rack or squat rack, but then you find out that the company doesn’t make the attachments / accessories that you want.

No problem! You should be able to find a compatible attachment or accessory, as long as your rack is made with one of a few standard configurations.

Compatibility

The key specs are:

  1. The tubing size of the uprights, typically one of: 2″x2″,  2″x3″, or 3″x3″.
  2. The hole diameter in the uprights. These fit pegs of diameter 1″, 5/8″, or another size. This is actually the peg diameter. Even though we would say 1″ holes, the hole is a hair larger, like 1.02″.
  3. The hole spacing in the uprights, ie: the distance between holes on center. This is only an issue for larger attachments that use 2 holes, with a peg and a locking pin. 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.

When slightly wrong sized attachments are ok

An attachments can fit in a larger hole, but it will be able to wiggle and tip down a little.

Similarly, attachments can fit onto slightly smaller tubing than what they were designed for. This can be less bad than the wrong hole size, because you can glue shims (UHMW plastic is best) to the inside of the attachment’s bracket to make it fit.

Some attachments work well enough even if they’re loose. Some don’t have enough pressure put on them to make a safety issue, like a rope anchor, but it could still rattle.

The steel gauge (wall thickness) of rack tubing does not factor in. The tubes are fabricated to match the right outside diameter.

When you should not use the wrong sized attachments

I don’t recommend you use certain safety-critical attachments designed for a larger hole or tube, such as J-hooks, steel safety arms, or plate holders, unless you have a good way of retrofitting it to stay snug. Use some common sense, visualize it, and you’ll get the idea.

You could run into poorly welded attachments. If you’re stoked to get those new crazy cheap J-hooks and your heart falls into your stomach as you find it doesn’t fit very snugly, well, it probably fits the same on that manufacturer’s own rack. Attachments as a rule don’t fit perfectly snug, but better brands like Rogue and Rep Fitness have the highest and most consistent quality, in contrast to the gamble you may be taking on a cheaper brand like Titan Fitness or some Amazon-only brand.

List of Power Rack Attachments by Size

These are ordered smallest to largest.

For a lat pulldown / low row cable system that works on almost any power rack, see the well-designed Spud Inc Pulley System.

Not listed here are complex attachments and accessories that will not fit any other racks, such as those that mount on the top or bottom crossmembers or need the rack to be a specific width between uprights. Examples are special pull up bars or rack extensions.
