Here is a guide that shows you step-by-step how to re-adjust your shower glass door to stop it from rubbing:
STEP 1
Place wood shims under the glass door, one at each end of the door.
STEP 2
Loosen the screws on the clamp of the top hinge. You may also loosen those at the bottom if necessary
STEP 3
This allows you to adjust the door upwards and toward the wall, creating space between the glass door and the adjacent glass panel.
STEP 4
Place a wooden shim in this space.
STEP 5
Tighten the screws.
