We have developed our NEW PRO Dome 10" cast aluminum dome/strainer. The PRO Dome will offer the quality customers expect from Marathon Roofing Products as well as the convenience of removing only one screw to clean out the drain. The PRO Dome is powder coated and also offers an extra layer of security to your installed roof drain. We also have our NEW Powder Coated Aluminum Clamping Ring. Both products can be upgraded to be used on any of our drains.
