Overview


Hercules RetroDrain

Designed to replace existing drains in all roofing systems. The onepiece spun aluminum body and heavy-duty cast aluminum dome and clamping ring provide strength and durability. The drain flange has a depressed sump area for improved flow and to facilitate water drainage from roof surface.

One-piece Seamless Body: 0.125" (3 mm) spun aluminum with 12" (30.48 cm) drain stem length, and an extra large 17.5" (44.45 cm) diameter flange that allows positive attachment of roof flashing membrane.

Strainer Dome: Available in two options: 7" (17.78 cm) tall cast aluminum (pictured), or 5.5" (13.97 cm) tall cast aluminum SuperDome with screw down lid, to secure against vandals.

Clamping Ring: The heavy-duty cast-aluminum clamping ring ensures a uniform compression seal of the membrane for strength and durability.
