I got these for my Titan Fitness T3 j cups. The fit was good and it saved me from having to upgrade the j cups. The one mounting hole makes it to where they can be knocked off to the side. A better design would be if it wrapped around on the sides.

Had these on titan rollers. It was a good added protection for the bar to keep from banging on to metal when re-racking.

I’ve got these on my Titan roller jcups and they’ve done a very nice job of doing the thing that they do. And they look sleek. I’ve got red ones on the black jcups.

They have a very secure fit to my Titan T-3 j-cups and were easy to install. I love the pop of red, and I’m happy about the extra protection they give my barbells.

Had these on my RML cups back in the day. They do the job, if you have a 3d Printer could prob make your own.

The Aperture Engineering J-Cup Protectors are a must for anyone who has standard J-Cups with little to no UHMW plastic. These J-Cup protectors will protect the knurling on your precious barbells from any metal-on-metal contact. These are 3D printed and made from high quality plastic/filament.

These are fine and mostly good but it’s fairly easy to knock them off or at least out of place. I think these would be better if they were made of rubber instead of plastic.

The did not have these available for the PR-1100 V1 that I really needed them for. I applied a lil love with a heat gun and glued them into place and they worked great. An excellent addition if your J-cups are junk

If you have crap J cups these are a must to protect you bar. Easy to install and save the knurling on your bar. They pretty durable to. I smashed the bar into mine and while it cracked it's still hanging on.

These definitely get the job done protecting the lip on your j cups. Nothing super special about them, they are better quality than some other similar products I have seen from Etsy. The owner is also super nice. During my order there was a lost item (shippers fault not his). He immediately sent a replacement and was super nice throughout the process.
