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.

I have have 3d printed j cup protectors on several pairs of Rogue Jcups between my monster lite and monster days. Awesome way to add some color to your gym and help keep from bashing your expensive barbells into bare metal.
