Look and feel like they should last a long time. Had to have Rogue send me an adjusting kit to get them fitted right.

These are really nice to use and have some more adjustability when trying to move the bar around and when you rack it.

I love these j-cups. The only ones I had used previously were super cheap metal ones from an Amazon rack that scratched the hell out of my bar. When I upgraded to my beloved Rogue rack I chose these for the combination of thinness and bar protection and I have had no complaints. They fit snugly on the uprights and they are beefy but not so heavy that they are annoying to move. I don't have experience with versions of these from other companies to compare, but can definitely recommend these very highly.

These are great because they aren't as wide as the standard J cup. For people that squat with wide hands that extra little bit can be a big deal when it comes to not losing a pinky finger. They look much better too and the plastic protects the knurling on your bar

Big upgrade from the base model j hooks that come with the rogue monster racks, easier to shift the bar from side to side, gives more clearance. Much cleaner look

These things are beeeeeeeeeef. Love them. The 1” gives way more clearance in a Rogue rack side to side. They also hold up way better than my Ghost roller cups with aggressive knurled bars. The fitment is also spot on.

Got these with the rack, as they allow for more movement than the standard or 2" sandwich versions. They work with all my bars, Only time im not using them is when I use the rollers with a straight bar when benching and squating

These fit my REP rack without issue, there is not any additional slop as I anticipated going from an imperial based attachment to a metric based rack. They are indestructible and offer great barbell protection. Outside of my MM snap backs, these are my go to J Cups. There are others out there that are more premium like Bridge Built, Irwin Fitness, with rollers, etc., but these are more than sufficient and hardly a budget option!
