To determine whether your above ground pool has a wide mouth skimmer or a standard (small mouth) skimmer, the easiest way is to measure the skimmer opening on the inside of your swimming pool wall.
The Standard (Small Mouth) Skimmer Winterizing Plate fits all Standard Above Ground Pool Skimmers with inside dimensions of 5-7/8" x 5-3/8". The Wide Mouth Skimmer Winterizing Plate fits Wide Mouth Above Ground Skimmers with inside opening dimensions of 5-1/8" x 11-1/2".
