AZEK Solid Cellular PVC Mounting Block for 4" DryerWallVent

Custom “Recessed” AZEK Solid Cellular PVC Mounting Block for the 4-inch DryerWallVent. Details: 8.25 x 8.25 x 1 inch with a 4.25” I.D. hole in the center and two drilled holes for mounting screws. This mounting block features a half inch recess and is used as a “stop” for lap siding or stucco when it is appropriate. 

After the house wrap is applied, attach the mounting block over the dryer ducting hole with appropriate flashing and mount with corrosion resistant screws.
