RetroFit Roof Drains

Product Documents

Retrofit Roof drains feature a 2 inch-wide band of high density, expanding foam tape impregnated with asphalt that is factory applied in a compressed state around the drain outlet. The tape is designed to expand to approximately four times its compressed thickness, filling the space between the drain and the existing drain sleeve, making the connection watertight.
