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.

Hi David,
Thank you for your great guide. I had a question about the Monster Light Wall Mount Kit (link at bottom). I have a Rep PR-4000 and want to use this kit to mount my rack to the wall instead of bolting down. From what I can tell there might be an issue because of the width of my rack. The stringer this come with has 2 hole options to attach the wall mounts into. From what I understand Rep racks are 47” inches wide and Rogue racks are 49” wide. Any idea if this would be compatible?
https://www.roguefitness.com/monster-lite-rack-wall-mount-kit
Do you know if the 11/16 inch Titan Fitness 4 Pack Bolt-On Weight Plate Holder Attachments Fits X-3 and T-3 Series Power Rack, Weight Plate Storage will fit the 1 inch hole and 3x3 upright of the new Inspire Full Power Cage?
I bought the weight plate holders because a guy on the Costco reviews website said that the weight plate holders from Titan for the X3 fit the Inspire Fitness Full Power Cage but I now know that the hardware for the weight plate holder is 5/8 inches and was built for the X3 which has 11/16 inch holes and not 1 inch holes like the Inspire Full Power Cage has .
Titan recommended I buy their Titan Rack weight plate holder where the bolts are 1 inch wide but don't the bolts have to be slightly smaller that the hole on the cage?
The Titan representative told me the Titan Rack holes are 1.02 inches wide.
I am perplexed.
Any help would be great
thanks!
Hey Paddy Leather,
I am in the same boat as you. I have the Inspire full power cage and am looking for compatible weight horns. Have you found something that works yet? If so, please let me know what you ended up with.
I am considering the REP Fitness PR-5000 v2 weight horns, but I am not sure that they will work since REP uses 1.98 inch spaced holes and I am not sure what exact spacing Inspire uses.
Thanks!
Homebody
I have them on my Inspire rack and they fit very well.
Anyone have options for safety straps for a Rep PR-1000 power rack (3/8" pin holes)? Looks like the Titan T-2 series 26-in straps are compatible (based on this article), but they're sold out now. Any other options? Looks like most things are 5/8" pins...
Anyone know if the rogue monster trolley arms fit on Rep 5000v2 racks?
I think you left the Titan T3 Spotter arms for rigs with 2X3 tubing and 5/8 holes.
https://www.titan.fitness/racks/rack-accessories/t-3-series/t-3-series-spotter-arms/401093.html
Or I am wrong? I have a ordered a PRX Foldable Murphy rack 2x3 and holes are 5/8.
https://prxperformance.com/products/murphy-rack
PRX Spotter arms are $150 plus shipping and Titan is $99 and free shipping.
By Looking at the other accessories, it seems the T3 accesories will fit 2X3 5/8 holes rigs...
Added the Titan spotter arms, thanks! I don't know why I didn't have them on there.
I will start adding more attachments that use 2 holes, because Titan has now gotten in line with the exact 2" hole spacing.
So...you agree Titan T3 spotter arms will indeed fit the PRX Murphy Foldable??
Yeah should be good!
Does Rogue ES-1 need an update? The newer ones are 2x3 5/8" holes. No westside space, but all holes are 2" on center. That should make it compatible with Rogue Infinity attachments, right?
It looks like the ES-1 (Echo Squat Stand 2.0) uses 2x3 uprights and the Echo Power Racks still use 2x2. That's going to make things confusing for a while. They're saying the ES-1 is also 1/2" hardware. So it doesn't look compatible with either one.
https://www.roguefitness.com/rogue-echo-squat-stand-2-0
I think it's 2"x2" bases with 1" hardware, and 2x3" uprights with 5/8" holes and 2" spacing.
I just got the ES-1 2.0. The uprights are indeed 2x3 with 5/8 (.625) holes spaced every 2 inches on center. Infinity attachments (and retro-fit kits) are supposed to fit perfectly, and I would assume that Titan T-3 (I think that's right?) attachments should all fit as well now that their holes are 2" on center. The base of the rack is still 2x2" tubes, and has 2 mounting holes on the front of either side of the base. I think the holes on the base are 1/2 inch, though, instead of 5/8.
Ok, but if the holes are 5/8" then the hardware/pegs can't be 5/8". Rogue is making this confusing by suddenly giving hole size on the page instead of hardware size like they do with every other rack. Maybe they mean hardware size. Can you measure with calipers?
From Rogue’s description:
“…and now features the same 2x3" 11-gauge steel uprights and protective UHMW J-Cups as the Infinity S-Series…
The 70.375" uprights have 0.625" holes spaced every 2" on center on the front and back, and the base components and crossmember are constructed from 2x2" 11 Gauge Steel, with 0.5" hardware included.”
I don’t have calipers, unfortunately. But it seems like they’re giving a hole size for the uprights, and a hardware size for the base.(?)
To add a little more confusion, it also says this: 0.625 holes spaced every 2" (or 5/8")
I was wondering if the vulcan flat 3x3 flat foot rack is using metric measurements like Repfitness and if there accessories were compatible. I know that Roque stuff can go do both stuff but rep accessories do not fit well on Roque and I was wondering if Rep stuff would fit on the Vulcan flat foot
I believe the Vulcan racks are all exactly 3x3.
I’m looking at the ethos folding rack from dicks sporting goods. It’s 3”X3” and 11 gauge steel. I can’t find any attachments for it anywhere online and it doesn’t have holes like normal squat racks. Does ethos make attachments for the foldable rack (they do for the standard), and if ethos doesn’t, are there any products that would work?
Just a FYI, HulkFit is also 60mmx60mm with 1” holes.
Someone else reported the Hulkfit is 65mm. Do you have the rack?
I have the Hulkfit Power Cage, it's closer to 63mm.
63mm is as close to 2.5" as you can get, so we've got three conflicting measurements for the Hulkfit now. Anyone got calipers? I got a pair to measure all this kind of stuff. It's tough to nail it down with a tape measure.
Afraid not on the calipers :/ The picture was more to show I have the cage and did go out there and measure, but it was hard to take while getting it lined up correctly (hence the tape which kind of throws off the measurement). When I hold it in place with both hands and look at it, it's between 63mm and 64mm, closer to 63mm though.
Ok, I'm putting it into the 2.5" section now. All the Amazon comments seem to agree.
I ended up getting a caliper, the caliper says 60.2mm, I tested all 4 posts and it ranged from 59.3mm to 60.6mm depending on the post and where I measured the post. I thought maybe the caliper was inaccurate so I tested it on my Rogue Mil-Spec Echo Bumper Plates (because they have a strict +/- 0.2mm requirement) and was within 0.1mm to all the specifications listed for the plates I checked. I am going to contradict my previous statement and say the Hulkfit Power Cage uses a 60mm x 60mm post.
Based on that, do you know if the PowerTec Resistance Band Pegs for the PowerTec WB-PR cage would fit my Hulkfit Cage? (https://www.powertec.com/new-resistance-band-pegs-attachment-wb-pr16-rbp?gclid=CjwKCAjwoZWHBhBgEiwAiMN66d02s0FNPPbf44Q3-BJkshO3MtgN6Izxn6eHkNEy1eowcN6q_BVBjRoCnNkQAvD_BwE)
You have the PowerTec WB-PR cage listed as 60mm x 60mm, but I don't see that listed anywhere in the specs for the cage. I'd rather not drill any holes in the base of my cage for band pegs so that seems like an ideal solution if it will fit.
Great, I'm updating it to 60mm.
As for the Powertec, I believe someone somewhere said it was 60mm.
Those band pegs look like they might only fit the Powertec.
Any reason the Titan T-3 safety straps aren't on the compatiblity list? I own a bolt lighting series rack and want a set of safety straps, the only one I can find so far is the Titan T-3 version.
It's right there on the list, under 2x3 tubing, 5/8" hardware
Sorry about that! My old eyes looked right over it. Thank you.
