The Inter-Fab three step ladder with Sure Step treads is one of our best selling residential stainless steel 304 ladders (1.90" outer diameter tubing). It comes with three stainless steel steps with a slip resistant gray plastic top tread as well as 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 our Rust Buster sacrificial zinc anode to help protect your 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.
