The RF370 is an SL300 Series roof flashing for roofs with a 0 to 6/12 pitch, sold as a single flashing. It seals the roof penetration around the chimney pipe and sheds water away from the opening. Choose the flashing that matches your roof pitch. Always confirm the pipe size, approved components and clearances in your fireplace, stove or chimney installation manual before ordering. For steeper roofs, use the RF371. A multi-pack of 5 is available as RF370M.
