Irwin Fitness Roller J-Cups


"I can't go back to standard j-cups, especially with how easy it is to rack/unrack (even without a spotter) Perfect placement every time as well, not having to use any effort/grip to position the bar before liftoff"

"Roller J-Cups just make so much sense"


We have taken inspiration and input from the home gym community and designed our own return roller j-cup. When you rack your bar onto our roller j-cups due to the shape of the rollers the barbell will find its way back to the center of the cup EVERYTIME. One of the most important things when setting up for a lift is being able to position yourself in the same spot every time. Easily slide a loaded barbell side to side as it glides on our bar saving composite rollers (customers testing with over 700lbs on the bar and still gliding effortlessly side to side).

We have took it upon ourselves to eliminate some issues that other roller j-cups on the market fail to provide. Our roller j-cups offer complete bar and rack protection with UHMW being secured to all faced of the j-cup. The UHMW is found on the side clasp, backing, and front with our IFS logo machined into the plastic. 

When we initially released the idea about our roller j-cups, instant feedback was that what is currently available to the public on the market there is a lack of barbell protection on the lip of the j-cups. We have machined a front protector from a 1" block of UHMW that wraps around the front to avoid any unnecessary damage in the event if you hit it on a re-rack. 

adapter for 2x3" - 5/8" hole racks available upon request


Material Options:

Composite plastic - 3x the tensile strength of UHMW with similar wear properties

Metal Rollers - start off as a 2" metal shaft, machined to size and shape, proceeds to head into a electroless nickel phosphorus bath to be coated giving it a very attractive and distinct finish, where it finally receives heat treat which produces an extremely durability finish.

  • Finished metal rollers have a hardness rating ~900 VHN in comparison to regular stainless steel which will have hardness rating of ~150 VHN
    • 5/8" pins are threaded in and have a bright silver zinc coated finish
    • 1" pins are plug welded and have a powder coated finish
    • Our rollers are tapered towards the center which allows for the rollers to accept all bar sizes including specialty bars
    • Easily rolls
    • Slotted hole at bottom of the roller j-cup to allow the use of orange handle detent pins to lock into place
      • we have found during testing these aren't necessary as the roller j-cups stay in position for most cases
