This rugged step is made from maintenance free polyethylene and it will fit any above-ground pool up to 54" in depth. Double handrails and big slip-resistant steps make an easy exit for young and elderly swimmers alike. The Pool Step is designed to meet or exceed all NSPI standards for safety and swimmer entrapment. The unit is easy to assemble and can accommodate up to a 350-lb. swimmer. The step is perforated to allow water and chemical circulation and eliminate a dead water area. The patented design allows for easy installation and removal of the ballast weight for off-season winterization. Pool Step's top flanges anchor securely to any deck for a firm footing. The Pool Step ships by standard FedEx, so it is economical to order. Please Note: In order for Pool Step to sit properly, it must be weighted in place using approximately 40 lbs of sand (not included).
