The part that holds the bar, so the part that must not give way
J-cups are what your bar rests on before and after every set. They are the part you use most, the part you look at least, and the only one sitting directly above you on the bench press.
These CS-1 Standard J-cups are cut from laser-cut steel and rated for a 500 kg capacity. You rerack a loaded bar without listening to the noise it makes.
A UHMW lining that protects your rack as much as your bar
Every cup is lined with high density UHMW plastic. That lining absorbs the steel on steel contact at the moment you set the bar down.
Two concrete results. The knurling on your bar does not dull and your uprights do not get marked session after session. On a cage you keep for ten years, that detail is the difference between maintained equipment and worn equipment.
Exercises involved
J-cups are the starting point of everything done in a cage. Squat, front squat, bench press, overhead press, good morning, rack pull. Every time, they are what carries the bar between two sets.
Usage and safety tips
- Check that both cups are on the same hole number before loading the bar.
- Make sure each cup is fully engaged in its upright, with no vertical play.
- J-cups carry the bar, they do not catch a failed rep. Always use safety bars on heavy sets.
- Inspect the UHMW lining periodically and replace the pair if it is damaged.
