Standard J-Cups (1000 Series)

The knurling on my barbell hasn't left a single scratch on these since I mounted them—the UHMW plastic liners are doing their job perfectly. They lock into the uprights with a satisfying click, and the bar sits rock-solid during heavy squats.

The plastic inserts keep the bar perfectly stable when I re-rack after heavy squats, and they slide into the rack holes with zero wobble. Solid build for the price, exactly what my home setup needed.

The J-cups fit my rack's 1-inch holes perfectly with no wobble, and the rubber coating grips the bar firmly to keep it from rolling. The plastic inserts are a nice touch to protect the bar knurling.
