Patent number: 5573081Abstract: A molded rectangular top component of a stepladder is disclosed which incorporates an improved method of securely supporting a bucket or paint can at the top of the ladder. A recess in a second wall of the laddertop corresponds to and accommodates the arcuate shape of the bail of a bucket, and a hook is attached at the lower portion of the recess, which has the beneficial effect of moving the weight closer to the center of the ladder than on a protruding hook. The ladder top includes at least one slot in a first wall which extends from the ladder top through which accessories can be attached. The first wall opposes the second wall.Type: GrantFiled: June 29, 1994Date of Patent: November 12, 1996Assignee: Werner Co.Inventors: Frederick J. Bartnicki, Lauren S. Sherbondy, Donald M.
