Copper Retrofit Roof Drain

TRUFAST copper drains feature a 2" (51mm)-wide band of high density, expanding foam tape impregnated with asphalt that is factory applied in a compressed state around the drain outlet.

Sealant tape is designed to expand to approximately four times its compressed thickness. Just prior to inserting the drain, the installer removes the exterior compression tape and immediately sets the retrofit drain in place. The released tape gradually expands to fill the space between the TRUFAST drain and the existing drain sleeve, making the connection watertight.
