Abstract: There is provided an adjustable vent pipe support which is secured to a ceiling joist. The vent pipe support is height adjusted to provide a proper pitch for a vent pipe. An upper support member singularly supports one or more sized vent pipes. A lower member includes openings that allow the vent pipe support to be fastened to the ceiling joist. A transverse member is superposed over the ceiling joist for additional support. Spacers are provided between the transverse member and the ceiling joist to provide height adjustment. The upper pipe support member includes various radii to accommodate various sized vent pipes.
