This is the “Super Duper Ultra Gizzmo” which has the same sealed air cushion as a regular Gizzmo but it has a built in blowout tube. This product will fit almost every skimmer since it comes with two different size pipe threads with rubber gaskets, 1½” & 2″. The blowout tube acts as a suction line extension, giving you the option to use it while clearing your lines without the worry of having to lower the water in your pool. The Gizzmo also features a rugged cap and lug style grips around the top for easy handling. This “Super Duper Ultra Gizzmo” is designed to only last for one whole winter season.
