EPDM manufactured with conical steps and factory-applied pressure sensitive tape around the base.
Features
Use: Specifically designed for round, roof penetrations eliminating the need for field-fabrication. The large double-thick molded ribs, at the top of each step, offer superior tear resistance as well as a cutting guide.
Materials: Uncured EPDM (ethylene propylene diene monomer) with a pressure sensitive seam tape around the bottom.
Color: Black
