Product details

The Pentair WC37-503P is the skimmer lid extension collar for U-3 skimmers. It is the ring that sits between the skimmer body and the deck surface and gives the lid a level seat.

What it does

Skimmers are set at whatever depth the pool build put them, and the extension collar makes up the difference so the opening finishes flush with the deck. Once the collar cracks, the lid no longer sits square and either rocks underfoot or drops into the throat.

Before you order

Check that the skimmer you are working on is a U-3. Skimmer collars are not interchangeable between bodies, so match the skimmer first, and note this listing is the collar on its own rather than a collar and lid set.

Questions and answers

What people ask about this product, answered by our pool techs.

What is an extension collar for?
It makes up the height between the skimmer body and the finished deck, and gives the lid something to seat on at deck level.
Which skimmer does this fit?
It is listed for U-3 skimmers.
Does the lid come with it?
No. This is the collar only. The lid is a separate part.
Why do these need replacing?
They sit in the deck and take foot traffic, sun and freeze cycles. Cracked or crumbling collars leave the lid loose or sitting proud of the deck.
