Sandwich J-Cups

Sandwich J-Cups

The robust Sandwich J-cups are heavy-duty and a serious plus when using a safety squat bar. The beefy sandwich design, abrasion-resistant lining, and sloped backing protect your bar and you while re-racking.

I got these with my rack when I bought it on FB marketplace. To clarify, these are for the BoS light commercial rack (2.3”x2.3”). Since my rack has a unique upright size (not a flex- I want the 3”x3” some day), these are really my only option other than their roller, which I have as well. I love these for what they are. The sandwich style makes it a lot easier to rack and is softer on the bar. They are sturdy and are not going anywhere. From all the beating it has worn the J Cup down a bit but I have a beater bar so it doesn’t bother me and hasn’t seemed to scuff it anyways.

Have the Manticore version and this is only sandwich j cups I’ve had. Works great and has the UNHW to protect rack. Short mag pin to lock in j-up is a nice inclusion.

Very nice no frills J-Cup. Lined to protect the bar and a good shape to ensure safety. I use them regularly. I would choose them over some higher priced items.

Good j-cups for the price uhmw wears out a bit quick to my liking. Bon j-cups pour le prix le uhmw se détériore un peu trop rapidement à mon goût

Definitely a budget item with a very narrow UMHW. One bonus is the mag pin hole on the backside to secure it in place.

Like most BOS equipment, retightening of the nuts and bolts is required. The UHMW wears a bit quicker than you’d like if your barbell has decent knurling.

These are one of the more budget options for a sandwich style j-cup. I use them just for benching they work well and protect the barbell. There are better options out there but it will cost you.
