I was worried about the tallness of this lid but it worked out perfect. Love not having to wear gloves to clean our filters..Product exactly as described and fit perfectlyMy original cover was suffering from sun damage which burned away the gel coat layer and turned removing and installing the cover an itchy experience. This cover was a bit taller than the original and I was concerned that I would have to buy taller filters. I decided to try it with the original sized filters and found my filter actually works better. With the original cover Ii was getting about 20 lbs of pressure at the gauge. With the new cover I was getting 15-18 lbs and the return jets seem to be returning water with more pressure and the skim inlet seems to have more suction. I highly recommend this cover as a replacement.The lid on our filter tank split and pumped 16,000 gallons of water down the hill before I discovered it. I looked around for a new filter housing and discovered that I could buy just the lid which saved me quite a bit of $$$, so I bought it and after putting it on the old tank bottom it works beautifully. I couldn't be happier!Good fit, easy seapOrdered this to replace a cracked lid for my filter. Worked great - Nice to not have the sun faded and itchy top I have had for the past ten years. I have a 320 gallon per minute - I think gpm is how it is sized, but I know it is the 320 unit I have.Easy to install, unscrewed the pressure relief valve and put it on this unit without problem. Recommended purchase if you top lid cracks. Amazon had the best price, availability and quickest shipping I found anywhere on line.AwesomeExactly what I needed to get my pool up and running again.
