Abstract
An improved single unit multi-purpose roof penetrating curb. The curb is a plastic box with one large upstanding inverted cup-like section on the top surface thereof. Four smaller upstanding inverted cup-like sections are equidistantly spaced on the upper surface of the large cup-like section. The plastic box has a flange integrally attached at the base. The flange completely surrounds the perimeter of the box eliminating the need for separate flashing.
