The drain features an aluminum body with an extra large flange for positive attachment of the roof flashing membrane and four rubber O-rings to make a watertight seal. It’s available with either a U-Flow cast aluminum strainer dome and cast aluminum clamping ring, cast aluminum SuperDome, plastic dome or a RAC aluminum strainer dome. The most common sizes are the 2-in. and 8-in., but other sizes available on a custom made basis.
