GRP Internal Drain Outlet

GRP drain outlets are used to join a rainwater downpipe to the Fibreglass roof where the drain runs vertically through the roof deck.

All 4 sizes are 200mm long and come with a flange that allow for the selected connecting pipe diameter to fit over the top of our drain outlet.

For example, if 50mm is selected, this is the diameter of the connecting pipe. Our GRP drain outlet diameter will be slightly smaller (about 43mm) to accommodate the connecting pipe diameter.
