The Polypipe 75mm Half Round Gutter 90 Degree Angle (RM303B) is designed for homeowners and contractors seeking a reliable, leak-free way to navigate building corners within a 75mm Half Round rainwater system. It offers the primary benefit of precise directional water management for both new builds and renovation projects, though users should ensure they are matching this with other compatible Polypipe 75mm components to maintain a secure, weather-tight fit.

No, this fitting is specifically sized for 75mm Half Round systems.
While it may fit some other systems, it is designed for the Polypipe range and optimal performance is only guaranteed with compatible Polypipe components.
The material is UV-stabilized to minimize color fading, though some weathering may occur over many years of exposure.
Polypipe gutter systems are typically designed as a push-fit installation, though you should follow the specific instructions for your entire system's assembly.
This is a fixed 90-degree angle intended for standard square building corners.
Verify that you are using the correct 75mm diameter range and ensure no burrs or debris are obstructing the connection point.
Check that the gutter is fully seated in the fitting and inspect the internal seals for any damage or misalignment.
To install, ensure your gutter runs are cut cleanly at the required length. Insert the gutter into the angle fitting, ensuring that the rubber seal (if applicable to your system) is seated correctly to prevent drips. Always ensure that the gutter has a slight fall toward the downpipe to maintain positive water flow. For care, simply clear debris from the corner fitting during your routine autumn gutter cleaning to ensure the 90-degree bend does not become blocked by leaves or sediment.
