Oatey All-Flash No-Calk Roof Pipe Flashing/Galvanized Base

Exclusive 1-piece construction insures a positive leakproof installation every time. Elastometric collar allows the vent stack plenty of room for expansion and contraction. Glavanized base is made from 24-gauge deep drawing steel extra high with no seams. Easy-to-install, the flashing slips over the vent stack and automatically adjusts to pipe size and roof angle, and remains perfectly flat on the roof.
