Cast iron crosses and tees connect pipes where they intersect at the center of a structure. Cast iron fittings have a higher tensile strength than aluminum fittings. These fittings have a galvanized finish that provides some rust resistance, making them suitable for indoor or outdoor use.

Cast iron couplings join pipes in a straight line. Cast iron fittings have a higher tensile strength than aluminum fittings. These fittings have a galvanized finish that provides some rust resistance, making them suitable for indoor or outdoor use.

Cast iron elbows connect pipes where they intersect at the corners of a structure. Cast iron fittings have a higher tensile strength than aluminum fittings. These fittings have a galvanized finish that provides some rust resistance, making them suitable for indoor or outdoor use.

Cast iron mounts secure slide-on railing and framing structures to a surface such as a floor or wall. Cast iron fittings have a higher tensile strength than aluminum fittings. These fittings have a galvanized finish that provides some rust resistance, making them suitable for indoor or outdoor use.

Aluminum crosses and tees connect pipes where they intersect at the center of a structure. Aluminum fittings are lighter than cast iron fittings, which makes them well suited for use in structures that will be disassembled and reconfigured often. They will not rust and are suitable for indoor and outdoor use. They are nonmagnetic and nonsparking.
