The Wavin Osma SquareLine Gutter Angle (4T803B) is an essential component for professional installers and homeowners aiming to navigate 90-degree corners in a 100mm square guttering system. Its primary benefit is providing a secure, watertight transition that maintains the sleek aesthetic of modern rectilinear drainage, though users should note it is specifically engineered for SquareLine profiles and is not compatible with round gutter systems.

No, this component is exclusively designed for 100mm SquareLine systems.
The Flexiclip system is designed to create a watertight seal without the need for additional glues or sealants.
This fitting is a fixed 90-degree angle designed for standard building corners.
It is manufactured from high-grade, durable plastic suitable for outdoor drainage applications.
Yes, the components are designed for outdoor use and to resist degradation from sunlight exposure.
While the Flexiclip is designed for a permanent fit, it can typically be released by carefully disengaging the clip mechanism; consult local installation guides for specific release procedures.
Ensure the gutter end is inserted fully into the fitting and the Flexiclip is engaged correctly. Check for debris trapped between the seal and the gutter.
Verify that you are using 100mm SquareLine guttering. Remove any sharp plastic burrs from the cut end of the gutter before attempting to insert it.
Installation is simplified by the Flexiclip system. First, ensure the cut ends of your 100mm SquareLine gutter are clean and free of burrs. Align the gutter end with the angle fitting and push firmly until the Flexiclip engages, creating a locked, sealed connection. Ensure the gutter is properly aligned with the fascia brackets before locking the joint.
Compatibility is strictly limited to the Wavin Osma SquareLine range (100mm). Do not attempt to use this with other brands or rounded profiles as the seal will not be watertight. Maintenance involves regular clearing of leaves and debris from the gutter run; during inspection, check that the corner joint remains free of obstructions to ensure unrestricted water flow.
