Dam Buster Stretched R300-500 Rainhead With Fixed Receiver

Dambuster Stretched R300-500 Rainhead with Fixed Receiver – Wide Capacity Gutter Solution

The Dambuster Stretched R300-500 Rainhead with Fixed Receiver is engineered for high-capacity roof drainage where wider box gutters are required. Designed to suit 500mm box gutters and compatible with Dambuster’s range of side outlets (L-shaped or T-shaped), this rainhead provides a fast, secure installation without the need for adjustable receivers used in flat-back versions.

Built with the same height and depth as the R300, this model is stretched to the full R500 width (500mm) to handle larger water volumes while maintaining proven performance and durability.
