This internal vertical drain outlet for fibreglass roofing provides a secure and efficient connection between a GRP roof and a rainwater downpipe, allowing water to drain vertically through the roof deck.

The outlet is 200mm long and is available with four flange size options: 50mm, 75mm, 82mm, and 100mm.

IMPORTANT: The selected flange size refers to the diameter of the pipe you are connecting to. The actual outlet diameter is slightly smaller to ensure a tight and secure fit within the chosen pipe.

For example, if a 50mm flange is selected, this corresponds to the diameter of the existing pipe. The GRP drain outlet itself will be slightly smaller (approximately 43mm) to allow for a snug fit inside the 50mm pipe.
