Each QuadFlash boot from OMG Roofing Products accommodates up to four rooftop pipe penetrations ranging from 3/8" to 2" in diameter. The QuadFlash uses flexible EPDM rubber caps that move with building vibrations or shifting pipes, as opposed to rigid pitch pockets that can crack under similar strain. The spun aluminum base features dual Lok and Grip beads around the collar for a secure hold on the cap.
