ABSTRACT:
A ladder leveling chock system for maintaining a level surface for resting a ladder thereon. The ladder leveling chock system includes a block with top and bottom faces, an end face, and a pair of side faces. The top and bottom faces converge together at an end vertex extending between the side faces opposite the end face. The bottom face has a resiliently deformable surface provided thereon. The top face is designed for resting a lower end of a rail of a ladder thereon and has a resiliently deformable gripping strip coupled thereto for frictionally enhancing contact between the top face and the lower end of the rail.
