ABSTRACT:
To facilitate supporting drain pipes at a prescribed grade or slope, a hanger formed of inexpensive material adapted for nailing has a plate-like body provided with a through opening for a pipe and having on opposite sides thereof a graduated distance measuring scale in relief form whose scale graduations may register with the bottom edges of floor joists when the hanger is nailed in position on either side of a joist to establish the required slope of a drain pipe. The pipe receiving through opening may be perpendicular to the plane of the hanger body or may be angled relative thereto.
