Works but needs to be packaged better

Functionally works as intended and easy to move around, but packaging needs work, j cups were scratched when I got them

Thanks for your feedback! We’re glad to hear the product functions well and is easy to move. However, we’re sorry to hear about the scratched j-cups and the packaging issues. Please contact us at team@fringesport.com with details, and we’ll work to resolve this for you.

J-Cups

Great experience; the J-Cups fit on my Ethos rack just like the review said.....PERFECT

The only thing that I saw that could be an issue is a need of some safety feature to keep them from moving; my existing cups have a magnetic pin to keep them in lock

Too Expensive and Needs Better Urethane Protection

The ONLY reason I purchased these J-Cups is because I had a $70 store credit. Otherwise, I would NOT have paid this much for 3x3 J-Cups. In fact, I paid $35 for a pair of 3x3 J-Cups from Amazon that are actually better than these, and they used a softer rubber/urethane on all sides of the J-Cup to protect my barbells. Besides the high price, my other complaint is that the urethane may damage the knurling on my Power Bar because it's so hard. My REP Black Diamond Power Bar is leaving a line across the urethane that looks like knurling "dust" embedded in the J-Cups.

Follow-up: J-Cups Are Rock Solid—Fringe Customer Service Blows Me Away

First off, these J-Cups are sturdy, snug, and do exactly what they should: protect my rack and barbells like a champ. But honestly, as good as these are, the real story isn’t the gear—it’s Fringe’s customer service.The process had a few bumps (not Fringe Sport’s fault), yet the team went above and beyond. They weren’t going to be happy until I was happy. That kind of dedication? Rare. That kind of experience? Unforgettable.If you want high-quality gear backed by people who genuinely care, Fringe Sport is the place to be.

Bought on Flash Sale, Worth the $

They work great with my Rogue Monster Uprights. Flash sale price was right too. I wish I had bought another pair.

Solid Design, But Packaging and QC Are a Miss

I wanted to love these J cups. The design fits perfectly on my sporting goods store rack, and the build feels solid—just like the Fringe bar and plates I recently bought and love.Unfortunately, both the original pair and the replacement arrived damaged. The first was clearly unacceptable. The second had similar damage, just less severe. If I had seen either in a store, I wouldn’t have taken them home.This is a stark contrast to the bar and plates, which arrived flawless and clearly packaged with more care. I’m keeping these because I don’t want to go through the hassle again, but I can’t recommend them as-is. I hope Fringe takes another look at their packaging and quality control process, because the product could be great.

Works fine for a piece of metal

It’s a Jcup. It holds the bar. Gets the job done.Would be nicer if it had UHMW plastic where it contacts the rack and not just where it contacts the bar.

Heavy Duty J-Cups

These j-cups fit my Body Solid GPR378 power rack perfectly. They are heavy duty and the UHMW on all three sides protects my barbell perfectly. I highly recommend them for any 3x3 rack.

Great product

Fit great on my stinger (generic CAP) 3x3 half rack. 100x better than the j cups it had originally. These are much sturdier. It’s especially noticeable with 300lbs or more. Would absolutely buy again.

Just wish that there was something to protect the rack from being scratched.

The shopping experience was excellent but the product is scratching my rack as there is nothing on the inside of the J-hooks where it contacts the rack. As is, these would be a terrible choice if you were moving them around on the rack. I purchased them to just store a couple of barbells high in the rack when not being used.

Awesome j-cups

I have been looking for something that would work on my rack. It’s rather old so there’s not much out there as far as accessories. Then I found the j-cups at Fringe Sport. I wasn’t sure if they would fit perfectly but at least I knew they would fit the holes. I was almost right, they don’t exactly fit my rack, but with a small modification, they work perfectly!

The J-CUP is functionally working as expected despite there is cosmetic cosmetic blemishes on the UHMW. Customer service is excellent.

Good set of J-cups!

Positive experience. I bought them for my 3x3 half rack from DICK’S Sporting Goods and they fit just right (a little loose, but it’s okay). I would definitely recommend them to anyone who wants another set of j-cups for their rack

Nice J-hooks

We bought these for an extra set for our Ethos power rack. They work and fit great.

The J-Cups are designed and built for our 3x3 rigs and squat racks, but they will fit many other brands of rig. Please note the pin size is 24.5mm and is not powder-coated like the rest of the J-Cup, but chrome-plated instead. 24.5mm is .96", so if your rack features 1" holes, these J-Cups WILL fit.
