Abstract
A two-component mold assembly for molding an opening within a concrete wall that provides access to a piping system supporting a sprinkler. The first component is an insert that is mounted on a concrete form, and the second component is a cover that slidably fits over the insert to define the opening in the concrete. The cover plugs the piping system during fabrication of the concrete wall and is removable from the opening in the hardened concrete after the concrete form and the mounted insert are removed.
