This part is unique to certain pools of various years. You must verify the part number with the packing slip that came with your pool and measure your track (rails) width. This will only work if your pool uses 5/8" rails. It measures 7 1/2" wide by 2" 1/4" deep. It is only used on oval pools on the bottom of the side verticals. It will not work on the bottom of standard verticals.
