Poor fitting for the monster lite series. Still waiting on the kit to be sent to make it work properly. I’m surprised the fit for the rack is not better when first purchased considering the price.

The tolerances on these are excellent and they fit into place just right and have no play so that there is no rattling. The construction is excellent and they work great. I got the duffalo bar inserts and swapping them out for the original inserts was very simple. These are well designed and masterfully constructed and are a very worthwhile upgrade for any squat rack!

Massive upgrade over standard J cups and they look great in the white!

I really like these, and I don't lift very heavy. The protection for the bar, the overall quality (SS pins), and the protection for the rack all add up to one thing for me: worth it.

Beautiful out of the box, very snug fit and they work exactly as expected. The one flaw they have imo is part of the actual design itself. The roller sits so slow relative to the welds that your barbell collar can end up making contact with the welds before the bar makes contact with the roller. This can lead to chipped paint on the sides as well as damage directly to the collars of your barbell. Not a huge deal imo for the simple fact that I don't mind being a bit more careful but my wife who is newer to lifting ended up chipping one of the jcups the first day I had them just by racking the bar after seeing how it felt to use them. Again not a huge deal to me but something to consider if you're going to spend the extra 100 on a color of your choice. I would still buy them again and would still recommend them.

I am still working on getting these to fit my RML3 rig that I bought in 2018- sadly the original set is too small with the plates and still too small with the kit they sent- would like to make it work. Will addend the review if we find a work around but super sad they are not usable yet

I got a set of these j-cups with my 490C Charcoal edition and they are super solid. I’m actually having the opposite issue of most of the reviews here… my set of cups are so tight that I have to bang on them with a dead blow hammer to get them to seat all the way. I’m hoping that they will wear in a little bit and loosen up without damaging the finish on my rack. Moving the cups up and down will get tiresome if they don’t wear in. Otherwise, they are solid, a great idea, and the hooks themselves are nice and smooth.

This is a great product; I recommend fully reading Rogue's Description and Reviews to make sure you understand what options will work best for you when ordering. As such, I wanted to provide some detailed feedback on my purchase. I have a Rogue Monster Lite Wall Mount rack in Rogue red. One thing that attracted me to these J-Cups is the built-in protection to ensure your rack does not chip or dent since I paid extra for the fancy paint job. I owned the J-Cup and J-Cup 1" sandwich versions before Rogue added rack protection. I used Plastidip previously to help prevent wear and tear with moderate success. These are very solid; the stainless steel pin makes them slide effortlessly when repositioning. Like other reviewers, I had one that fit perfectly snug and one that sat a little loose on the rack. I opened a ticket with Rogue Support, and they immediately sent out a plastic replacement kit with three size options that replace the rearmost guide support and some shims to use if needed. This fixed the problem immediately. (Some feedback to Rogue: putting little size markers on the rear of the plastic components would have made identifying the sizes a little easier.) I purchased the steel rollers; again, as other reviewers have stated, the trade-off is either cleaning the plastic off your bar or having marks on your bar. Not spinning the bar while racked is just not something you will ever do. I have a Rogue red Ohio bar; I plan on buying a stainless steel bar to use with these J-Cups and use the red one for deadlifts, etc. In the meantime, I bought a roll of APT's 3" UHMW (Ultra-high Molecular Weight) Polyethylene Tape from Amazon. It doesn't look too bad, and it resists the abrasion when the bar rolls in the cups. The way it sits in the cups, you only need to cover 3" to protect your bar when sliding from side to side. The portion where the bar rests on these cups is a little shallower than what I was used to with the 1" sandwich version, and the bar does automatically reseat itself in the forward position, which I really like. Overall, it's a great product; the shim fix from Rogue should get everyone back on board with this being a 5-star product.
