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 3 Compatibility Specs
The key specs are:
The tubing size of the uprights, as above, typically one of: 2″x2″, 2″x3″, or 3″x3″.
The hardware/peg diameter that fits into the holes in the uprights, as above. One of 1/2″, 5/8″, 3/4″, or 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.
When Slightly Wrong Sized Attachments are Ok
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.
When You Should Not Use the Wrong Sized Attachments
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.
Attachments Using 2 Holes
A large number of readers have asked about attachments that use a locking pin to secure the attachment into a second hole on the rack’s upright. If the hole spacing is the same, it’s fine. Normally the question involves a brand that uses metric hole spacing, in which case it is not compatible either direction with imperial (inches) hole spacing. As much as you want it to work, no, under most circumstances you won’t get the locking pin in. The difference is about 1/16″ on the first hole, and the difference widens with each successive hole.
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.
List of Power Rack Attachments by Size
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.
The size categories below are ordered smallest to largest.

2×3 Tubing, 3/4″ Pegs
Sunny Health & Fitness Power Zone Power Cage
No other brands match this size. The attachments in the 2×3, 5/8″ peg section above should fit this rack well enough.
2×3 Tubing, 1″ Pegs
Fitness Reality X-Class Light Commercial Rack
No other brands match this size.
50x80mm (1.97″x3.15″) Tubing, 5/8″ Pegs
Rep Fitness PR-3000 (discontinued)
3×3 Tubing, 5/8″ Pegs
Rogue Monster Lite, Vulcan Flat Base Power Rack, Stray Dog Strength, Griffin Fitness GR3 Lite*, Bells of Steel Hydra, Rep Fitness PR-4000*, Titan X-3*, Body Solid GPR400 / SPR500 / SPR1000**,
* The Titan Fitness X-3, Rep Fitness PR-4000, and Griffin Fitness GR3 Lite racks use 75x75mm tubing, which is 2.95″x2.95″, or about 1 millimeter difference vs true 3×3 inch tubing. Their attachment brackets are generally made large enough that they are compatible with 3×3 tubing except as noted. They both use 50mm (1.97″) hole spacing. For the reverse situation, you can use true 3×3 attachments on these 75mm racks, if the attachment does not need to fit tightly the way some such as roller J-cups need to.
** The Body Solid SPR1000 takes 5/8″ pegs facing the front/back, and 3/4″ pegs on the sides. Many of its attachments are made to fit the side holes, which are incompatible with any other racks.

3×3 Tubing, 3/4″ Pegs
American Barbell power racks, EliteFTS Collegiate / R3
See the 3×3, 5/8″ section above for more attachments that will fit these racks well enough.

* The Titan Fitness, Rep Fitness, and Griffin Fitness racks use 75x75mm tubing, which is 2.95″x2.95″. Their attachments are generally made large enough that they are compatible with 3×3 tubing. There have been reports of Titan’s all-steel J-cups and UHMW-lined J-cups not fitting over 3×3 tubing, but their other attachments should fit. Titan and Rep both use 50mm (1.97″) hole spacing.
Universal Fit Attachments
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.
Rear Rack Extension and Foot Stabilizer Fit
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!
General Recommendations
For the best compatibility going forward, I highly recommend getting a 3×3 rack taking 5/8″ pegs or 1″ pegs, compatible with Rogue Monster Lite or Monster, respectively. Other companies try to fit those sizes to be compatible.
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.
As mentioned about specific brands in the charts above, you might want to steer clear of racks that have metric sized tubing that is not truly 3×3 inches even though that might be what they advertise.
Does the Titan X3 monolift arm work on the Rep Pr 4000?
Yes, the Titan X-3 attachments fit the PR-4000. I’m going to combine those two tables into one shortly.
Hello, I am looking at the Ethos Power Rack 1.0 from Dick’s Sporting Goods. Seems like a good rack for the money. However, I cannot find any specs on the tubing size or hole size. I also cannot find any accessories available like plate storage or multi-use pens (e.g., for attaching bands). Are any of the accessories listed above compatible with the Ethos Power Rack?
It’s listed in the section of 3×3, 1″ hardware. The Rogue Monster attachments will fit.
Does anyone know if the PR-4000 Crossmember is compatible with the Titan X3?
I have a TDS brand 72 inch power rack made in 2014 – 2 inch x 1 inch holes. TDS currently doesn’t have their jammer arms in stock/doesn’t have an ETA on when they will make them again. I can’t seem to find a set of lever arms that fit these measurements … anyone have any clues? Willing to go DYI/purchase multiple parts. I don’t wanna throw the whole rack away just for jammer arms!
OK, so I bought a Rogue Monster Lite Slim rack for my upstairs home gym and I’m outgrowing it and thinking of building a bigger gym outside in a steel shed about 20x14x9.
I bought the spotter arms and landmine for it. So its 3x3x 5/8s I can see from the chart.
My question is do they fit any of the REP or Titan racks?
Yes, it will fit the PR-4000 or Titan X-3
does anyone have any experience using or adapting a rep fitness lat pull down for a pr 5000 on a rogue rm 4.
Interested in this as well- anyone do this? or on a X3.
if you knew how far apart the holes were on center on the rear stabilizer on the rep equipment you could tell if this would mount up on the rogue uprights. if this worked i could adjust the upper rear crossmember to the height the piece from the lat pulldown. i had to cut my rogue uprights a few inches because i failed to measure my garage ceiling prior to purchase. im guessing they are 95-96 inch tall now and you could just move the rear cross member down a little bit if they rear stabilizer holes match up
sounds doable. Maybe dropping a note for someone to measure the distance on r/homegym
Once again, I appreciate your help. My barbell turned out great thanks to your article on that. I thought the Rep PR 4000 could accept Rogue Monster Lite Attachments, and that the PR 5000V2 could accept Monster Series attachments and vice versa. Is that incorrect?
Yes, should work. There was some confusion with the metric sizing but it’s close enough. The hole spacing will be a little off if it’s an attachment using 2 holes and a lock pin.
I have a 100 inch Rep Fitness PR 5000 V2 rack. I’m looking at purchasing the Titan, Titan Series extension kit. Do you know if the holes on the Titan uprights align with the holes on the Rep Fitness uprights?
Highly unlikely that the extension kit would fit. The rack would have to be virtually a clone in several dimensions, and I don’t think it is.
Confirmed that multiple Titan X-3 accessories work with my PR-4000 including dip attachment, wrist roller. Also, RML channel storage pair works perfectly on PR-4000 a well. Pretty much any attachment with just one 5/8 hole works perfectly
Thanks for sharing, good to have the confirmation!
Might consider adding Fray Fitness FFB2 Fold Back Wall Mount Rack to the list of 3X3, 11g, 1″ list. I just purchased and installed. It’s the same specs as the Rogue RML-3W. Fray has great customer service, as well.
Added, thanks! I’ve been trying to get more details on their other racks for months, but they haven’t responded to any of my emails.
Good stuff
Numbering as well
Good job on the use of space! Was it easy to install things just right and get the feet just barely sliding over the floor?
Yeah. Easy to install with a little thought ahead of time. I have a sloped garage floor, as everyone does. But there is enough ply in the wall connectors to the arms to go up and down, so when folding the rack in, I just have to pick them up a little off the floor and fold them in. When extended, one side is of course not flush with the ground because of the slow, but I just have a couple of wood shims I put under the post. Not a bog deal. In case it helps anyone installing one of these things without the stringers (I didn’t see them necessary), I just basically set up the whole system including my wood stringers on the garage floor, measured everything out, tightened everything down, etc., then picked it up and put it in place against the wall, shimmed up the one side and leveled it, and screwed it in to all the studs, etc. Hardest part was lifting it and moving it because that beast is heavy, but I got it done. If I had a second muscle man on hand to lift and move, it would have been easier.
will the Titan “complete pulley package” fit on a REP PR 4000 rack?
I do not see where the Vulcan Power Rack – Flat base has been categorized. Vulcan claims the rack is 3×3 11 gauge steel and 5/8′ westside holes. Are the accessories for this rack compatible with the Rogue Monster Lite?
Added! Their Flat Base rack is 3×3, 5/8 holes, so Monster Lite compatible.
awesome – thanks alot
Isn’t the Rep Fitness PR-5000 V2 a 3×3 with 1″ HOLES?
Yes, close enough, just a little under 3×3
Trying to convert SM-1 to SM-2 and use my 70 inch pillars for the back. I want to attach the 70 inch to 90 inch(power rack) without buying both conversion kits. Is it possible?
This should be possible, but it sounds like you should consider coverting your SM-1 to the half rack. You may need to contact rogue to see if they will sell a modified HR update package so it includes the 90 in uprights and utilize the 70in you already have.
Would the Titan attachments for the T-2 Series (specifically the T-2 monolift) not fit the Rep PR-1100? I figure the .03 inch of tube size should not matter that much but it says requires 2 inch hole spacing and I can’t tell why
Hi David. Just wondering I have the bodycraft f430 seems verŷ limited to what attachments available apart from bodycraft own dip bars and j hooks. Do you know of any other brands that would fit it for jammer arms or any good different attachments to add some variety . 2×3 and 1/2 inch holes
Hi any update on this from anyone
I’m interested in trying to attach a REP Fitness PR-4000 Lat/Low Row Attachment to a Rogue RML-390F Flat foot monster lite rack. The Rogue rack has 3×3” x 92” high uprights with ⅝” holes. The outside distance between rear uprights is 49” so the 43” REP rear base stabilizer seems like it could fit the Rogue rack (inside dimension between rear uprights: 49” – 2X3” = 43”). That assumes the holes would line up. The Rogue uprights are an inch shorter than the REP’s so I would need a one inch shim at the top. REP is coming out with a belt squat attachment that will work with the Lat Pull Down unit. This combination would be considerably cheaper than the Rogue offering. Anyone have any comments?
I’m so interested in this too. I want to mount the rep lat pulldown to a Titan X3. The inside dimensions on the pr4000 is 41” vs 42” for the X3. Stabilizer is 43”
Has anyone attempted this with some shims/adapters?
You’re kind of effed if you own the stainless steel drop-in style racking, as seen with the Legend Fitness Ultra Pro lineup, Hammer Strength power racks, dynamic Ultra line up, and the elitefts vs multi full lineup. Tried to order a set of elitefts multi-full rack j-cups along with the off-set pair to experiment with my Legend racks, but they are not making them due to covid-19.
Yep, York has some similar to that too, and I’m not sure if any of them are even compatible with each other.
Will any of the squat safety straps fit the Valor Fitness Bd-11 power rack?
Thanks
