My father in laws 20 year old pool doesn't have a weir door on the skimmer. I can't tell what make of a thing it is. Are they all the same size? I'm going to measure it anyway...
Jim what do the pins grab on to? I would think a good wave would push them out if they are just pressure fit against the side walls?
I just measured the width and height and then bought two universal doors that would fit.. They have spring loaded pins that hold the door tight at the bottom and let it pivot..
