Some of our stock of these Comp Jcups were manufactured with a slight lean to the left or the right. Performance wise they are great and being offered at a huge discount due to the manufacturing flaw. The Giant 3X Competition Jcups offer softer nylon protection that is sandwiched together. This protects your barbell's knurling from damage because there are no metal-to-metal contact points.
The 3X Jcups make racking your barbell easier. This product is only guaranteed to be compatible with our 3X series racks with 1" diameter holes. (75mmx75mm tubing)
