The CMP 25526-000-000 Skimmer Extension Collar is a white replacement extension collar used with compatible in-ground pool skimmer collar and lid assemblies. This collar helps raise or level the skimmer cover area when the finished deck surface sits higher than the original skimmer collar height.

Important Notes

  • This item is the skimmer extension collar only.
  • Skimmer lid, skimmer basket, weir door, faceplate, screws, complete skimmer body, gaskets, and deck materials are sold separately unless otherwise stated.
  • Verify your exact skimmer model, collar size, lid style, and deck opening before ordering.
  • This collar is not universal for all Hayward, Pentair, CMP, SwimQuip, Sta-Rite, vinyl, fiberglass, or gunite skimmers.
  • If the skimmer body, deck ring, lid, or surrounding concrete is damaged, replacing the collar alone may not correct fitment or safety issues.
  • Do not leave a skimmer opening uncovered or unstable during pool use.

Installation Notes

  • Confirm the skimmer model and collar dimensions before installation.
  • Remove the existing skimmer lid and inspect the collar, skimmer body, and surrounding deck area.
  • Clean away dirt, debris, old sealant, loose concrete, or damaged material before fitting the collar.
  • Dry-fit the extension collar before final placement.
  • Make sure the skimmer lid sits flat, secure, and level with the finished deck surface.
  • Do not force the collar into an incompatible skimmer opening.
  • For deck remodels, confirm final deck height before permanently setting the collar.
  • Have damaged skimmer bodies or unstable deck openings repaired before normal pool use.
