Abstract
A form for molding a footing at an end of another form for molding a pillar. The footing form includes a rigid hollow base having a bottom, an open top and a side wall extending upwardly from the bottom to the open top, and wherein the bottom is larger than the open top. A sleeve extends upwardly from the open top of the base for being received within an end of a pillar form. The footing form also includes protrusions extending laterally outwardly from an outer surface of the sleeve for frictionally engaging an inner surface of the pillar form, yet preventing the inner surface of the pillar form from engaging the outer surface of the sleeve. Accordingly, the overall contact area between the footings is reduced for easier application of the pillar form onto the sleeve of the footing form.
