First, slide the shower doors to one side of the tub, then remove the old shower door guides.
NOTE: If the screws are difficult to remove, apply some WD-40 to loosen them up.
Next, tilt the new 10-139 Bottom Hook Guide into the track base. Align the hook guide at a 90-degree angle as demonstrated below.
Align the existing spacer with the new hook guide before reinstalling the door and attaching the spacer and guide securely.
If you are not certain that the 10-139 is what you need, send pictures of your guide removed from the door to SWISCO.com’s discussion board and our team of experts will be happy to research what products might work for you.
