2024 Update – Moved a few brands to metric sized sections where they should have been
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, which I don’t like to list unless there are no other options, are the worst and might be unsafe. Most other brands are somewhere in the middle or sometimes as good as Rogue.
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.

See the 3×3, 5/8″ section above for more attachments that will fit these racks well enough.
Titan’s TITAN Series, Rep Fitness PR-5000, Vulcan Strength Racks (except Flat Base Power Rack), Griffin Fitness GR3, Giant Lifting 3X Series, Fringe Sport Osprey Power Cage, Fray Fitness Savage Series, Get Rx’d Goliath rack
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.
There have been reports of Titan’s all-steel J-cups and UHMW-lined J-cups 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 attachment 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, even if the tubing size and peg size are a match, 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. If you found a case where they are perfectly compatible, please leave a comment!
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 in the beginning stages of abandoning their 2×3 racks in favor of 3×3. Other manufacturers have noticed and likely will 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. That said, many people know what they’re getting into and choose to buy those.

Hey man not sure if anyone has already posted this or not but I found some more attachments that work for the Ethos Power Rack. There’s a company called InspireFitness and they have a Power Rack that is exactly the same as the Ethos Power Rack. They have a few attachments that they will sell you if you message them and ask to buy the attachments separate from the rack. Landmine, dip bars, battle rope & band peg attachments. I ordered them and all worked excellent.
why did you buy from inspire and not look at the list from other ocmpanies like titan or what not. is there something you felt inspire offered better, more cheaply than the other attachment offerings?
Hello, could you add ATX?
FYI this guy on etsy makes adapter to make it so any 3x3 will fit snugly on a 2x3 and even 2x2's.....https://www.etsy.com/shop/3DSolutionsTX?ref=simple-shop-header-name&listing_id=1010530559
That's cool, I'll have to share it!
Will the rogue shrimp trawler fit a Rep PR4000? This attachment isn't listed. Thank you so much for the help!
That depends. I put a rogue monster shrimp trawler on a pr-5000 with no problems because the holes were oval, not round, on the trawler. If the 5/8” version is the same oval shape, then you should be good. You should confirm with rogue
Same issue as other attachments that use 2 holes. Metric vs imperial hole spacing.
So I have the rep 5000 power rack
I was looking at Rogues reverse hyper attachment for their monster racks
Would this fit on my 5000?
Thanks for all of your great posts btw
Nope, hole spacing is off. Metric vs imperial.
Please add Griffin Fitness GR3 Lite to the guide.
Will do, thanks. Looks like they're directly compatible with Monster Lite.
I can confirm the Titan T3 Spotter Arms do work with the PRX Performance 2x3 racks. The fit was very tight, but I found some light sanding makes a strong friction fit. There are three plastic pads that contact the rack posts. Two are on one side of the post with the one remaining pad on the other. I took the pad from the side that only has one off by unscrewing two screws. I then lightly sanded the back and screwed it back on the arm. The arm now fits the post with a strong friction fit making the pin unnecessary. I should note, I also tried Fringe’s spotter arms, but their design interfered with the stabilizing arm at the height I needed for my bench. The arms also were pretty banged up when they arrived. Ultimately, the T3 arms are a cheaper option at half the price of PRX’s own for their 2x3 racks.
Are there lever arm attachments for a 2x2 cage with 4/5 peg holes? Thanks!
I think the market isn't really big enough for someone who has the cheapest size cage (2x2) but wants an attachment on the expensive side like that.
I have TSS, do 1" attachments forcefully fit the 7/8 holes on their 3x3?
Any idea if the Straydog Half Rack Band Attachment fits in the Rep PR500 Uprights?
