The RedLine AFR is a tool-free system that provides for maximum allowable flow for gravity-based, open-channel roof drainage systems. The drain is installed from the rooftop to not disrupt building occupants and has a one-piece seamless body for strength and durability, as well as a heavy-duty cast-aluminum strainer dome and clamping ring. An extra-large flange, available with TPO or PVC coatings for hot-air welding, allows positive attachment of roof flashing membranes.
