Abstract: A mold is provided for forming a concrete column having at least one recess formed therein, as molded. The mold includes a tubular housing having an inner surface and a recess form having an inner and an outer surface. The recess form is mountable in the housing at a desired location on the inner surface of the mold housing. The recess form is preferably generally a ring The ring's outer surface corresponds to the shape of the housing's inner surface so that, when the ring is mounted in the housing, there are substantially no gaps between the outer surface of the ring and the inner surface of the housing. The ring has a slice through it, so that the ring may be expanded and pried out of the groove or recess molded in the column once the cement has set. Preferably, the slice is off-set from a radial line drawn through the ring. The ring is secured in place in the mold using screws.
