Marathon ULRD Roof Drain

The Marathon ULRD Roof Drain is made of a durable injection-molded PVC body and is ultraviolet stabilized for long life. The molded polyethylene dome strainer bolts into the clamping ring. A clamping ring is an optional addition that may be required to help provide additional bonding of the membrane to the drain and roof deck. Available in 2-inch, 3-inch, 4-inch, and 6-inch outlet sizes. Choose between buying your roof drain with or without an overflow ring.
