ABSTRACT:
This application provides an attachable non-slip ladder support for and on an upper rung of a ladder with a typical stile and rung construction. This support has a shell-like member having an internal configuration which is sized and adapted for slidable mounting on this upper rung. Intermediate this shell-like member and fixedly secured to its outer surface is a resilient non-skid member which is typically of sponge-like material. This member is secured by adhesive, rivets or the like. Clamp members are used at each end of this resilient support to removably secure the support assembly to the rung in the selected desired attitude. These clamp members insure that the support is not moved during use so that the resilient portion protrudes ahead of the stiles.
