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.

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.

Though I'm not a fan of the 3" hole spacing, I couldn't turn down the deal I got for a Body Solid GPR378 rack. Are there any attachments that fit this rack other than those made specifically for it by Body Solid?
I heard back from Body Solid - The GPR378 has 1 3/8" holes, 3x3 tubing, and 3" hole spacing. So no other brands will fit it well.
That rack is 3x3 tubing, 3" hole spacing, but I'm unsure of the hole size. The holes look larger than 1" to me. I'm checking with Body Solid and hopefully will have an answer Monday!
Thank you David for posting all of this very useful information. Enjoy the hang gliding. I remember as a young Army Infantry Officer at Fort Ord, CA, in the very early 1970s we managed to get the Army to spring for a few hang gliders for use at the base's rec center. I still enjoy the memories of soaring over the edge of the pacific off the hills south of Monterey and Carmel. Be safe when hang gliding and enjoy the hell out of it.
My question is compatibility of attachments to use on a Sorinex XL Power Rack. As you know, it is a 3 x 3 with1 inch hardware and one inch holes spaced (I think) every two inches on center. I am assuming that pretty much I can use any attachments from other companies that they use on their 3x3 1 inch platforms. I guess the only issue is the difference in the width for attachments going across the rig. Sorinex is 47" across while Rogue and others are 48" across. I would like to use some Rogue attachments, like, for one, their plate storage posts that have only the one screw through the upright directly into the post.
Thanks again for taking the time to provide all this useful information.
Hi Cal,
We still fly at Fort Ord, over the 6 miles of dunes! Good to hear you survived the crazy early days of hang gliding.
Right, you would run into an issue with attachments that spread across two uprights. It's rare that they will fit right on anything but the intended model. This is one reason people end up buying Rogue or Titan Fitness racks, because they make so many attachments for their racks. Rogue even more so because you can count on them being in business for a long time and fully testing their products for safety before releasing them.
Hey David, your site has been soooo helpful! I'm curious if you know if the Rep Fitness HR5000 is compatible with Rogue's rack-mounted reverse Hyper? I'd like to avoid taking up more space with a separate Titan or Rogue RH.
H Chad, the Rogue reverse hyper attachment is 43" wide, too wide to fit inside Rep HR-5000. That's pretty much one of those attachments that will only fit a Rogue rack.
You probably already saw this, but it looks like Rep Fitness's new PR-5000 is 5/8th attachment size like the Rogue Monster Lite. I bought the PR-5000 last November, and they said (over email) they aren't developing certain attachments like mono-lifts for the 5000, which they are for 4000.
EDIT - This is an incredible useful resource so I wanted to contribute in a small way, haha. Thanks for keeping this so up to date!!
From Rep's pics and description, the Rep PR-5000 has 5/8" holes on the top and bottom to fit hardware, and several more 5/8" holes at the top. Further down, like from 7ft high and down, it's 1" holes. This could make some attachments like monolifts not fit right when they use the higher holes.
Is yours different? That's strange that they would change the configuration of a given model.
Apologies! I mistyped the name. They just released the PR-4000 which has 5/8th holes for attachments and 1 inch holes for hardware. It looks like they flipped it from the PR-5000 that has 1 inch for attachments and 5/8th for hardware.
You are right. I will need to check what holes I would need to use the monolift on to see how things would fit. I wish they just used one size (either 5/8ths with 3x3 or 1 inch with 3x3).
Great, I'll add the PR-4000 to the page!
But the PR-4000 wouldn't have 1" hardware either. It's all 5/8". Maybe you saw the 1" hole spacing.
I checked my PR-5000 and it has 5/8ths from about 6 feet up.
So the Rep PR-3000 rack has that much of an odd sizing that nothing else is compatible? Trying to find a monolift and other items not offered by Rep fitness to work with this rack.
Pretty much. Some things could be retrofitted with wood or plastic shims, but I wouldn't mess around with trying to retrofit something weight-bearing like a monolift without really knowing what I was doing.
In case anyone is wondering, the Titan X-2 weight storage posts do indeed fit the Rogue ML series. Rogue's 4" between the center of one hole to another is precise, whereas Titan's is hair shy of 4", but it works nonetheless. Obviously, you need longer bolts since the bolts included with these are designed for a 2" W post.

Thanks for sharing!
ok so. They are sooooo close. Do you think the 2x3 rogue stuff or even fringe will fit the 2x3 Rep fitness rack?
Not likely They're made to a pretty snug fit. The only ones I expect would be fine are like the Rogue Landmine that uses a bolt (you can pick up a longer bolt if necessary) or something that doesn't wrap tightly around the 3" part of the tubing.
Will the Rep safety straps 36" fit my 36" deep Titan X-3?
The Rep straps are made to fit 30", too short for the Titan X-3.
Is there a solution to get s straps for the X-3 / 36"?
Looks like Titan hasn't made straps for their 36" version yet. You probably have to wait for those.
Hey Dave,
Are these Safety Spotter arms compatible with the 3x3 1" Rogue Monster racks?
https://www.valorfitness.com/RG-19-Safety-Spotter-Arms_p_529.html
Yep, those Valor ones should fit perfectly! They look like they might be really nice spotter arms if the measurements are done just right and the quality control is on par. According to my records they came out with those one year ago. Let me know what your assessment is if you get them!
Thanks for putting this information together. I have a Powertec rack, the square tube size measures 2 3/8" x 2 3/8". Is this considered a standard 2" x 2"? I am looking at the Titan T-2 accessories and trying to make sure they will fit before purchasing. Thanks.
I'll correct that. The Powertec tubing is more like 2.5" x 2.5" as you say. The attachments for that size are very limited.
Also, Powertec is probably metric at 60mm / 2.36". The American vs metric sizes are a complication that I haven't addressed yet. But you can generally ignore the small difference and assume any attachment made for 2.5" x 2.5" will fit over the outside well.
