The UltraLift Spa Cover Lifter will fit virtually any size and shape of spa. With patented sliding mounting brackets, the UltraLift lets you mount to the deck, patio, or directly to the side of the spa and adjust to fit into the tightest spaces. Made from aircraft grade aluminum, the UltraLift virtually eliminates twisting and flex, making it possible for just one person to open and close. Manufactured with cold-rolled steel brackets that are e-coated and powder coated, they provide years of reliable, trouble free service meaning no plastic parts to weaken or break. Constructed from 1 1/4" diameter tubing, the UltraLift works to protect the seam of your cover, making it last longer. The UltraLift comes with easy-to-follow instructions, complete with diagrams and a full parts and tool list.
