Abstract
A concrete mold core assembly for casting catch basins and the like has outwardly facing form panels disposed to form a box with at least two corner members being located at diametrically opposite corners of the box between spaced adjoining edges of the panels and a lid overlies the ends of the form panels and corner members. Each corner member provides opposite side surfaces defining a tapered wedge that matingly inter-engages with the spaced adjoining edges of the form panels such that when the corner members are moved outwardly the core assembly is expanded into its casting condition and when moved inwardly the panels and members are stripped from the hardened concrete. The lid is coupled to the upper ends of the corner members to be raised to casting condition when the members are moved outwardly and lowered to be stripped from the hardened concrete when the members are moved inwardly.
