The Pool Lift Model AG72 was specifically designed to lift people into and out of above-ground high wall therapy pools walls. After raising the seat, the assistant turns the seat while helping to lift the patient's legs, then turns the valve handle to lower the seat inside the pool. The stainless-steel plate at the base of the cylinder is bolted to the floor, and a stainless-steel bracket around the top of the cylinder is bolted through the top pool flange. The standard seat has two arms and a seat belt is included with each lift. Refer to the our dimensional worksheet for the measurements we need to know before building this model lift for you.
