In stock and prompt delivery, thanks PST!
The little plastic spring clips work to hold it in place and are a bit fussy. They slide under almost invisible micro lips.

We have an older inground pool and were struggling to find the correct skimmer basket but found this one on PST Pool Supplies website. It was PERFECT! It was the correct size and was exactly the same basket as we originally had. We couldn't be more please with the speed at which it arrived, the quality and it being exactly as shown.
I made the mistake of trying a non-OEM flow sensor found on Amazon for $28 first. Don’t waste your money as it doesn’t work; red lights remained on and no chlorination. This is an OEM (Pentair) part and once installed all red lights went out and chlorinator was back in business.
Great price and fast delivery to Western Australia- saved me having to replace the whole filter.
gasket was exact replacement for old gasket that had deteriorated. leak fixed and hot tub back in action
split nut worked perfectly and fixed hot tub leak on 2 inch pipe.
used lube tube to place gasket and new collar on hot tub 2" pipe to fix a water leak. All good and hot tub up and running.
