Our lift uses hydraulic arms to lift the spa cover off the spa and out of your way. You fold over half the cover onto the other half and the arms do the lifting. Once the cover is lifted the hydraulic arms lock in place. Some lifts require two to four feet beyond the spa to store the cover, but the lift we offer needs only inches. Using only inches allows for use in gazebos, up against walls, and indoor applications. The lift we offer is capable of adapting to most installations, whether your spa is inground or in a cabinet.
