Abstract
A ladder attachment which cushions the shoulder of a person carrying the ladder. A foam cushion is bonded to a base which slips onto either side rail of the ladder. The base is shaped to mate with the channel shape of the ladder rail and has inturned lips on the edges of its sides which hook over the flange edges of the rail. A resilient foam pad is interposed between the base plate of the base and the channel web to apply a force which assures that the lips remain hooked on the flange edges.
