Got these to protect a new cerakote barbell. Installation was easy, and the fit is perfect. Appreciate the various color options for adding a little pop to my squat rack.
I tend to roll the bar to the edge of the j-cups when setting up for bench press, and I was getting concerned about metal to metal contact and grinding away at the knurling. These were easy to install, look nice, inexpensive, and protect my barbell. I got two pairs to cover all of my j cups.
I'm very happy with the purchase.
I can recommend this product, as it has protected my barbell while in the j-cups. Sometimes I might need to shift or spin the different specialty bars or olympic barbell I own, this stops damage to the knurling or bare metal of the barbells. The cost is low compared to others and is durable enough to not break easily. These look to be 3d printed like most or all of their products seem to be.
