Power Rack Attachments & Compatibility – Master List

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.


The key specs are:

  1. The tubing size of the uprights, typically one of: 2″x2″,  2″x3″, or 3″x3″. All 2″x3″ racks have the 3″ sides oriented the same direction.
  2. The hole diameter in the uprights. Attachments need to have the same size pegs, ie: 1″, 5/8″, etc.
  3. The hole spacing in the uprights, ie: the distance between holes on center. This is only an issue for larger attachments that use 2 holes, like with a peg and a locking pin. 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

Attachments can also fit in larger holes. For example, Rogue’s Infinity attachments with 0.63″ pegs can fit into the Titan X-3’s 0.69″ holes. When an attachment is made for a larger hole, it will be able to tip forward a little because the rear hole does not secure it.

Similarly, attachments can fit onto slightly smaller tubing than what they were designed for. For example, Titan attachments for 2.5″ tubing can fit onto Powertec’s 2.4″ tubing. This can actually be a better situation than the wrong hole size, because you can glue shims (UHMW plastic is best) to the inside of the attachment’s bracket to make it fit perfectly.

Some attachments work well enough even if they’re loose. Some don’t have enough pressure put on them to make any difference, like a rope anchor.

The steel gauge of racks does not matter. The difference in dimensions is too minuscule to count.

When you should not use the wrong sized attachments

I don’t recommend you use certain safety-critical attachments like J-hooks or steel safety arms designed for a slightly larger sized hole or tube. Depending on the fit, they may tip forward or wiggle too much.

Weight plate storage attachments can present a similar problem, where the storage peg won’t stay perfectly horizontal if it’s too loose a fit.

You could run into poorly welded attachments. If you’re stoked to get those new crazy cheap J-hooks and your heart falls into your stomach as you find it doesn’t fit very snugly, well, it probably fits the same on that manufacturer’s own rack. Attachments as a rule don’t fit perfectly snug, but better brands like Rogue and Rep Fitness have the highest and most consistent quality, in contrast to the gamble you may be taking on Titan Fitness’ quality.

List of power rack attachments by size

These are ordered smallest to largest.

For a lat pulldown / low row cable system that works on almost any power rack, see the well-designed Spud Inc Pulley System.

Not listed here are complex attachments and accessories that will not fit any other racks. These include any attachments that mount on the top or bottom crossmembers or need the rack to be a very specific width. Examples are special pull up bars and almost any vertical barbell holders.

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.

ok so. They are sooooo close. Do you think the 2×3 rogue stuff or even fringe will fit the 2×3 Rep fitness rack?


Will the Rep safety straps 36″ fit my 36″ deep Titan X-3?


Is there a solution to get s straps for the X-3 / 36″?


Hey Dave,
Are these Safety Spotter arms compatible with the 3×3 1″ Rogue Monster racks?



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.


New add for you, rep just added strap safeties for 2×3


I have a Sorinex power rack, which I repped from CL. Sorin standard HOLE size is 1 inch and 1/16 to mm, which of these brand accessories can I buy that would be 100% compatible with Sorinex power rack hole dimensions.

PS: Sorinex power rack attachments & accessories are out of my budget and I am looking to add from any other brand, (1) Y Dip assist, (2) landmine attachment (3) Safety spotters pair / Saftey arms.


David, Thanks for your prompt reply, Yes – I was meaning to say hole size is 1 1/16 (this as per Reflex fitness who built Sorinex racks in the past).

Tubing size: 2″X3″ TUBING


Hole size: 1 1/16 inches


My setup & rack pics if it helps identify what Sorin rack this is? https://imgur.com/a/BoGBt


Hi David, It was my bad, the uprights are 3″ x 3″ with a hole size 1 1/16″, can you please advice on the attachment compatibility.

Cheers and thanks in advance.


Useful article, thanks. I don’t see the Rep PR-3000 storage posts, land mine and safety spotters listed as compatible with the R3 but would assume they are based on the numbers.


The Titan X-2 is 2”x2” with 11/16 holes. One thing that I know that’s compatible is the T-3 multi-grip pull-up bar because I have it. One thing I think that’s compatible is the T-3 landmine attachment because it goes through the 2” side of the bar.


I actually found this blog because someone referred to it on the subreddit r/homegym. I think posting this question on that subreddit would get you a ton of the information you’re looking for. I’m not very good at the Internet so just to be clear, r/homegym is a forum on reddit.com.

Hello, I was wondering if having 5/8 attachments for a 1 inch hole power rack would be a problem? I would want the titan fitness t3 weight holders for my 2×3 power rack, but wondering if I should worry about that.
