Our portable 2 story fire escape ladders are designed to provide a safe, reliable means of escape from a second story window located in a Residential or Residential Commercial Building. Our ladders are designed to attach to a window by hooking over the main outside wall of the building, and then extend down to the ground. We carry a variety of 2 story fire escape ladders to fit outside walls between 9.5 and 20 inches thick from Kidde and Saf-Escape.
