11815 FLASH GALV 11/2-3

Exclusive one-piece construction insures a positive leakproof installation every time. Elastometric collar allows the vent stack plenty of room for expansion and contraction. Galvanized 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.
