The Inter-Fab three step economy ladder with white High Impact Plastic (HIP) treads is one of our top selling residential stainless steel 304 ladders (1.90" outer diameter tubing). It comes with three white plastic treads and two rubber bumpers to protect your pool wall. The rails are 20" on center apart. If you have a salt pool we recommend that you purchase two of our Rust Buster sacrificial zinc anode to help protect each rail from rust. Also available in several powder coated colors: white, earth, coppervein, hammertone gray or light gray. You must purchase the anchors and escutcheons separately. Made in the United States and has a three year warranty.
