Pylex 12091 Strip, Paper, Black

Made from standard tarred roof paper, this impermeable band prevents wood decay. Larger than the simple joist, it diverts water to each side. Offers maximum protection for your deck. Do not waste anymore energy or time cutting bands from a large roll of 48 in (for the roof). This band is installed in a wink - just unroll it on the roof structure and staple it.
