2026 Update – Revamped entire guide to link to manufacturer pages that list all compatible attachments, so that you can quickly browse the full selections.
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.
Table of Contents
The key specs are:
The tubing size of the uprights, as above, typically one of: 2″x2″, 2″x3″, or 3″x3″.
Racks made in China usually use metric sizing. This applies to a lot of brands featured here. They don’t advertise the fact, and you would have to ask them or run into the problem yourself. The tables they are organized in identify them as such.
The hardware/peg diameter that fits into the holes in the uprights, as above. Varies from 1/2″ to 1″. Going by the peg diameter is more consistent across brands than the hole size that is cut somewhat larger than the peg.
The hole spacing in the uprights, ie: the distance between holes on center, as above. This is only applicable for attachments that use 2 holes, the second using a locking pin.
2″ spacing is becoming the standard. 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.
An 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.
Similarly, attachment brackets can fit onto slightly smaller tubing than what they were designed for. 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. Some attachments work well enough even if they’re loose. Some don’t have enough pressure put on them to be a safety issue, like a battle rope anchor, but it could still rattle.
Lastly, the steel gauge (wall thickness) of rack tubing does not factor into compatibility. The tubes are fabricated to an outside diameter spec.
For 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.
I don’t recommend you use load-bearing attachments that don’t fit quite right, such as J-hooks, steel safety arms, or plate holders, unless you have a good way of retrofitting it to be snug enough. Use some common sense, visualize it, and you’ll get the idea.
In many cases attachments that use a locking pin to secure the attachment into a second hole on the rack’s upright won’t line up the same on all racks. Normally this is the difference in metric and imperial (inches) hole spacing. As much as you want it to work, under most circumstances you won’t get the locking pin in. The offset starts at 1/16″ per hole and widens cumulatively.
If you’re thinking of foregoing the locking pin or buying a thinner one, and you have to ask for confirmation on whether it’s safe, you probably shouldn’t do it.
Rogue has among the best and most consistent quality. Cheap Amazon-only brands are the worst and might be unsafe, and we avoid promoting them when possible. Most other brands are somewhere in the middle or sometimes as good as Rogue.

Slightly smaller than 3″x3″, and pegs slightly smaller than 1″. Generally compatible with 3×3 racks. The attachments here with a locking pin using a second hole, such as spotter arms, can even sometimes fully fit on 3×3 racks because the smaller peg size somewhat makes the attachment drop a little lower and reach the slightly wider spaced hole to lock into.
An exception: There have been reports of Titan’s regular J-hooks not fitting over 3×3 tubing.

For a high and low cable system that works on almost any power rack, see the Spud Inc Pulley System shown above.
If you only need a high pulley (for lat pulldowns and tricep pushdowns), see Giant Lifting’s pulley system for a much lower price.
This Rep Fitness dip station above fits on almost any rack with 1″ round safety bars (thanks Anthony!). The rack needs to have at least 21″ depth between the front and back uprights, which is the case for all freestanding racks and most floor-mounted racks except the most shallow ones. The rack’s hole spacing does not matter, as the bottom part of the attachment simply rests against wherever the lower safety bar is.
There are a couple solutions for power rack strap safeties if you can’t find a match. If you can get a brand of them with brackets that fit your rack but the straps are the wrong length, get two 2″ Stren-Flex slings of the right length to replace them with. They are extremely strong, with pertinent info labeled and a chart on that webpage with the pound ratings.
Your second option is a pair of Spud Inc suspension straps that hang off your rack’s top crossmembers.
Multiple questions on this in the comments prompted me to add this section.
You generally can’t add a rear rack extension – usually to accommodate weight plate storage – made for a different brand. The height of the holes off the floor and the rack width would have to be precisely the same.
Similarly, with extension feet meant to stabilize a rack, the holes would have to be precisely the same height off the floor, or they would float and defeat the purpose.
I have heard reports of people using these across brands, but in every case it seems the user made some modifications to make it work.
For the best compatibility going forward, I highly recommend getting a 3×3 rack taking 5/8″ pegs (Rogue Monster Lite compatible) or 1″ pegs (Rogue Monster compatible). Even you never buy a Rogue product, they lead the way in things like this.
Rogue appears to be de-emphasizing their 2×3 racks in favor of 3×3. Other manufacturers have seemed to follow suit. This doesn’t mean that nobody will make racks with 2×2 or 2×3 tubing. I believe that there will be a market for those lighter and cheaper racks for a long time, and they are not necessarily bad racks. The 3×3 attachments sell much better and are more numerous, because people who spend the extra money for a 3×3 rack are more likely to soup it up.
You might want to steer clear of racks that have metric sized tubing. They are harder to fit attachments on. Some of them fit ok.

David, this is an awesome website. Thank you for this, have purchased some awesome attachments for my ETHOS 1.0 using your list. I do have one question...will these fit onto the ETHOS 1.0 PowerRack?
https://www.titan.fitness/racks/rack-accessories/titan-series/titan-series-vertical-barbell-holders/400549.html?gclid=Cj0KCQjwtamlBhD3ARIsAARoaEyFhrbcePj5DtHKdq5umIafcnPrHCJ2fK9CjbMOcW_9DsYf-IEvytoaAuazEALw_wcB
This is my ethos. with titan bar holder.
Did you ever purchase these? If so, did they work/fit?
It's unlikely the metric spaced holes will line up right, unless the Ethos is made to metric specs too?
I have the Titan T-3 I bought the Rogue Matador and Rogue Landmine (because of a previous version of this list) and both fit perfect. Not sure why the list was changed.
This is an excellent list. Thank you for this.
I think this is an excellent list but I think it's worthy to include the Northern Lights brand of racks here if Amazon racks are included. They're a popular brand up here in Canada due to high shipping costs (or inability to ship at all) to Rep/Titan/Rogue/etc. and I have their crossbox rack which is 2x3 & 5/8 (not sure if Imperial or Metric) and they have attachments like monolifts for the 2x3 5/8 footprint at a cheaper price (at least converting retail price from CAD to USD). I think they also have distribution in the US but I'm not sure about that.
Hello David! Great list! One correction: in the 3" x 3" section, the Giant Lifting 3x series power rack is also a 75mm box tubing, not true 3". I emailed their customer service and they confirmed.
It would be useful to split the 3" section into true 3" and into 75mm sections!
Thanks, I'll get that corrected!
I might take your suggestion and separate out the metric and imperial sizes into their own sections. I had them separated out like that at one point. I started combining them again with the idea that it might be more helpful because most (but not all) attachments fit well enough either direction to be usable. But of course there's the 60mm ones that are nowhere near any imperial size, so maybe it makes more sense to be precise with all of them.
Interesting, this is a tough choice for me, it's real frustrating that marketing copy that says 3" with 2" spacing is often incorrect, especially on racks that are so highly publicized like the REP and Titan racks. On the other hand, with one-peg utilities fitting on both, that's real useful to know.
I wish people would standardize on the 3" steel and have that be! I assume the problem is that overseas supply chain will provide cheap 75mm box steel tubing, while a 3" box steel is a speciality item in europe and china?
Thanks for this incredible website BTW!
I guess the metric is either cost related or more common in Chinese factories. Then the US companies get sunk costs before they measure it and find out 3" is nominal.
there's exactly three countries still using imperial measures: the US, liberia, and myanmar. I'm guessing most people can't find the latter two on a map and they don't export anything of consequence, so it's basically just the US. i suppose China could equip themselves with the necessary tooling, software tools, engineering models, and all of the associated supply chain requirements just to keep us happy, but it's just not cost-effective or practical for most things. Global supply chains are forcing one industry after another to convert. You don't have 1/4 bolts on your car anymore and you don't have a 302 cubic inch engine. Rogue still makes much of their stuff in the US, so they can keep this up for the near term. I wonder how many KG sets of plates Rogue and Rep sell here in the US...
I am looking for a 43 inch cross member with 5/8 holes on inch centers, is there such a beast?
Will the Athena Cable system fit any other rack system, such as the Bells of Steel Hydra rack?
It looks cool, doesn't it. I'm going to have to look into this. I bet there are people who have tried rigging it to other racks.
Are these actually tested or just based on measurements? I'm curious about the Titan Series Adjustable Lever Arms on a PRx Profile Pro. I recently got some Hulkfit lever arms that are 3x3 with 1" peg thinking it would fit. Unfortunately, it seems like the powder coating on the PRx is pretty thick and makes it slightly over 3x3, while the Hulkfit arms' bracket is pretty exactly 3x3. Worried about the same outcome with the Titan lever arms and have heard they have a pretty hefty restocking fee, so hesitant to test it out.
Hi i have just purchased Rogue RML-690 power rack and am looking for best lat pull option which will fit i am in Australia if it helps Kind regards
I have a Verve commerical power rack, which is an Australian brand with 75mm x 75mm uprights and 16mm peg size. From what I can see Rep PR4000 attachments use the same dimensions. Anyone know what I should look out for if I'm looking at getting one of those cable lat pulldown/low row attachment that comes over the back of the rack. Will I have trouble using a different brand?
