ABSTRACT:
A new Safety Ladder for providing a ladder which may be safely and stably positioned relative to a building. The inventive device includes a pair of side rails, a plurality of spaced rungs supported between the side rails, a pair of adjustable legs each telescopically extendable from a lower end of one of the side rails, and a pair of standoff arms each pivotally coupled to an upper end of one of the side rails. A first foot adapted for frictional engagement with an underlying surface is pivotally coupled to the free end of each of the adjustable legs and a second foot adapted for frictional engagement with a roof of a building is pivotally coupled to the free end of each of the standoff arms.
