ABSTRACT OF THE DISCLOSURE A mold for forming an opening in a masonry wall is disclosed, being formed of three detachably-attached segments; two of the segments are equal in length but oppositely configured. The third segment is secured at its opposite ends to the first two segments at their respective non-meeting ends. The meeting ends of the first two segments are also secured together, whereby the mold can be collapsed inwardly. The mold is mounted in a masonry wall by a truss and collar slidably engaged thereon, the collar being selectively retained in position by an orthogonally-projecting bolt fixed at one end to one of two spaced-apart frames between which cementitious material is poured. The mold is formed in its outer periphery with a perimetrical groove adapted to retain the inner portion of a gasket seal, so that the latter can be permanently embedded in the cementitious material as the wall is cast.
