It lays along the edge of a solid in ground winter cover and holds it against wind without the liner risk that comes from weighting a cover with blocks or bricks. The double chamber design means one puncture does not empty the whole tube. Fill each chamber about three quarters full so the ice has somewhere to expand.\u003c\/p\u003e\n\n  \u003csection class=\"gliwthd-spec-section\"\u003e\n    \u003cdiv class=\"gliwthd-spec-heading\"\u003eSpecifications\u003c\/div\u003e\n    \u003ctable class=\"gliwthd-spec-table\"\u003e\n      \u003ctbody\u003e\n        \u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eGLI Pool Products\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct\u003c\/th\u003e\n\u003ctd\u003e10' Double Chamber Water Tube, Black\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eModel \/ MPN\u003c\/th\u003e\n\u003ctd\u003e500010WTDHDBLK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003ePST-500010WTDHDBLK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGrade\u003c\/th\u003e\n\u003ctd\u003eHeavy duty, thicker wall than the standard tube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConstruction\u003c\/th\u003e\n\u003ctd\u003eDouble chamber vinyl, heat sealed seams\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClosure\u003c\/th\u003e\n\u003ctd\u003eScrew cap fill plug on each chamber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFill Level\u003c\/th\u003e\n\u003ctd\u003eAbout 75 percent, leave room for ice expansion\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUse\u003c\/th\u003e\n\u003ctd\u003eWeighting solid winter covers on in ground pools\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBest For\u003c\/th\u003e\n\u003ctd\u003eHard freeze regions and multi season reuse\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSeason\u003c\/th\u003e\n\u003ctd\u003eFall closing through spring opening\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003c\/tbody\u003e\n    \u003c\/table\u003e\n  \u003c\/section\u003e\n\n  \n  \u003csection class=\"gliwthd-faq\"\u003e\n    \u003cdiv class=\"gliwthd-spec-heading\"\u003eGood to Know\u003c\/div\u003e\n    \n    \u003cdiv class=\"gliwthd-faq-item\"\u003e\n      \u003cp class=\"gliwthd-faq-q\"\u003eWhat makes the heavy duty tube different?\u003c\/p\u003e\n      \u003cp class=\"gliwthd-faq-a\"\u003eThicker vinyl.
