Product review (5 stars): Nice product
This was the easy part to slip on when change. Please buy a new outer clamp before starting the job. The spring clamp rots out because of contact with the soap. I did not buy one and will have to buy a new one and install it.
The inside spring clamps that holds it to the tub went on easy.but the outer clamp was a struggle.and the hardest to install. It is actually a two person job to put the clamp on. You could put it on with that $67 tool or use a couple of spoons like I did and an extra hand to prevent these from rolling off the metal lip on the door panel. The spoon do two things. First they help the cable into the rubber slot by opening it, then it prevents the cable from slipping out when it tightens up while stretching the spring.
You will need to first line  up the spring on the bottom in the slot provide in the rubber. This will save you time from taking it apart and reinstalling it.
