This low profile spa cover lifter works where others can't. High quality, locking shocks do all the work.Constructed of the highest quality of materials and simple to install, the Cover Valet lifts and stores covers on spas set inside gazebos, those sunken into a deck or in tight spaces. Just 6-8 inches of clearance behind the spa is all that is needed. Powder coated steel and aluminum with zinc coated hardware, this cover lift is built to stand up to harsh environments. The Cover Valet has two heavy duty zinc coated metal frames, which attach to your portable spa cabinet or the decking next to your inground spa. Pneumatic pistons assist you whenever it is time to open up your spa cover. The Cover Valet has a one year warranty. Cross Reference:081048220, CV250
