This is the fire escape ladder that deploys easily from its storage box to a length of 14'. Unlike inferior ladders that require assembly or become tangled when extended, this ladder comes ready for use and folds compactly into its box for convenient storage. Its large, non-slip rectangular rungs provide sure footing, unlike lesser models that use slippery, rounded rungs. Fire-resistant nylon strapping connects each rung, making it more comfortable to grasp than chains or ropes. The ladder's rubber-tipped standoffs provide an easy foothold without damaging a home¿s exterior. Made from strong steel, it supports 375 lbs., exceeding ASTM safety standards, yet it is still lightweight enough for children or the elderly to use. For use in two story residences. Fits 6" to 10" wide sills. 12" W x 24' L x 5" D. (21 lbs.)
