Abstract
The wall jack may comprise a strongback coupler, a horizontal arm, a handrail holder, a support strut, and a support foot. The wall jack may be adapted to couple to a strongback of a concrete form. The strongback coupler may couple to the strongback by hanging on a bolt protruding from the strongback. The horizontal arm may extend away from the strongback coupler in a direction that is perpendicular to the concrete form. The support strut may brace the horizontal arm diagonally between a midpoint of the horizontal arm and the support foot pressing against the strongback at a location that is below the strongback coupler. The handrail holder may retain a handrail post in a vertical orientation. The wall jack may be used in groups of two or more to support scaffold planks or walk boards of a scaffold.
