A freeze-proof roof hydrant mounts through roof insulation, membrane, and decking with a ten-inch diameter opening and a support height of thirteen and one-quarter inches. Four mounting bolts secure an under-deck flange beneath the roof decking, clamping the assembly with three clamp screws. The hydrant features a one-inch national pipe thread inlet connected to a three-quarter-inch cold water supply line, with an overall height of forty-eight and one-half inches. A bolt circle pattern with four three-quarter-inch drill holes accommodates the hydrant base, guided by a standard support template.
