Ghost Roller J-Cup 2.0 Plastic Calibration Kit

The tubes that make up your rack uprights can vary by .03" (~1/32") above or below 3”. If you have racks from other manufacturers, particularly those made from metric tube, they can be .06" (~1/16”) or more below 3”.

Athlete preference for fit also varies.

As shipped, the Ghost Roller J-Cup is designed to fit on the most common tube size which is around 3.015" (3-1/64").

If you received the calibration kit that means that the fit is either tighter or looser than you desire.

Determine if your Ghost J-Cup 2.0 is too loose or too tight for your preference.

Remove the Clasp Plastic using the provided Hex Key and take note of what type of plastic was installed on your J-Cup by referring to the included parts list.

Note that your Clasp Plastic may have UHMW Tape Shims [4] installed on the back of it. See attached drawing for reference. If your J-Cup is slightly too tight, try removing this tape and checking the fit again. If still too tight, proceed to the next step.

With Clasp Plastic removed, slide J-Cup back onto Upright for testing process.

Note: In the next steps you may be using various thicknesses of plastic and tape to check the fit of your J-Cup. In most cases, you can check the fit without having to install/remove the plastic each time by simply sliding a plastic or tape piece into the gap while J-cup is on the rack.

If your J-Cup is too tight, proceed to Step 4.

If your J-Cup is too loose, proceed to Step 5.

If still too tight after removing tape, try a thinner Clasp Plastic- [1] if you started with [2], or [2] if you started with [3].

Use one hand to stabilize the J-Cup while the other hand slides the plastic in place as shown.

If too loose with a thinner plastic, try sliding in the 0.1” UHMW Tape Shims keeping the adhesive backer in place while testing fit.

Note: you may need 2 pieces of 0.1” UHMW tape stacked on top of each other.

If your J-Cup 2.0 is too loose, try adding a thicker plastic; [2] if you started with [1] or [3] if you started with [2].

If J-Cup becomes too tight with a thicker plastic, try adding a .01” UHMW Tape Shim to a thinner Clasp Plastic. Refer back to Step 4 to see depiction of adding UHMW Tape.

If adding UHMW Tape Shims to make the fit tighter, remove the adhesive backing and stick to left and right side of plastic. Press down firmly

Ensure the holes on tape align with screw holes on plastic.

Note: You were provided with many more UHMW Tape Shims than you will likely need.
