ABSTRACT An internally threaded mechanical-joint bell fitting for cast iron pipe is adapted to be screwed onto an externally threaded end of a plain pipe section. The fitting has an integral bolting flange circumscribing the mouth of the bell and preferably includes a circumferential water stop flange at the smaller threaded end of the fitting. The fitting also includes mounting pads at the threaded end for attaching a free-standing support structure. The support lower ends to brackets that are adapted in turn to be bolted to studs preset in poured concrete footings for a tank or building wall. The bracket feet are bifurcated so that each bracket can bridge a water stop barrier set into the top surface of the wall fitting. Peri- pherally spaced recesses, aligned with bolt holes in the bolting flange of the bell fitting provide clearance for heavy hex nuts threaded onto clamping bolts; so that two bell fittings can be used face-to-face to resist axial tensile forces acting on the joint, thereby eliminating the need for external thrust supports.
