The same j-cups that come standard with our racks. With an extra set, it allows you to set a pair up on the front of the rack as well as the back making transitions between exercises more fluid.
For any racks with 5/8″ holes and 2.3×2.3″ tubing.
Fits any rack with 2.3" x 2.3" uprights and 5/8" pin holes, including our Residential Rack, Utility Rack, Light Commercial or Brute Power Racks.
These J hooks are sturdier with a deeper hook than the ones that came with my squat rack. Unfortunately I didn't catch that the post that goes into the rack is significantly smaller then the holes in the rack. The holes in the rack are 1" where the post on the hooks is about 1/2". The photo is a little misleading, however my fault for not reading the description properly. I had sleeves built to go on the posts so they fit my rack. Other then that I really like them!
