Abstract
A flashing including an elastomeric collar with an inner surface and an outer surface and adapted to seal against more than one size of a vent pipe passing vertically through a central opening in the collar. The elastomeric collar has a circular base adapted for interconnection with a base member and a central opening including a first annular ring defined by a separation circle and a second separation circle, at least one additional annular ring outwardly therefrom that is frangibly separable from the first annular ring at the second separation circle and frangibly separable from the elastomeric collar at a third separation circle. Each annular ring selectively is removable by a pull tab that extends vertically from the outer surface of each annular ring at a location proximate to the separation circle of that ring with respect to the elastomeric collar.
