Poolmarket's Covermate Freestyle Cover Lifter is designed specifically for round, octagonal spas or hot tubs but will also fit square or oblong hot tubs up to 8 feet.
The Covermate Freestyle Cover Lifter has a height adjustable mounting base that simply slides under the spa or hot tub and enables the covermate freestyle to be installed on virtually any spa or hot tub. The weight of a spa or hot tub provides a massive amount of strength to support the bracket system.
It is pneumatically assisted and is and when in the open position, the CoverMate Freestyle positions the cover well away from the hot tub so that your use is not restricted in any way.
