The flat elbow turns the run left or right inside the plane of the wall, following a building corner or stepping around a window reveal. In North America this fitting is normally sold as a flat elbow rather than a horizontal elbow, which is the name used by most installers and distributors. This fitting is supplied in brown, moulded from the same colour-through PVC as the brown kit, so joints and corners stay invisible on the wall.

Where the building is brick or timber-clad, brown blends in where lighter finishes would glare. The shade was selected against common European brick tones, and it is moulded through the full thickness of the PVC so scratches stay the same colour as the surface. Pair this flat 90-degree elbow with the matching kit and a run that crosses brickwork, timber fencing or a brown fascia stays visually quiet from the street, with no repainting needed after installation.
Q: Is a flat elbow the same as a horizontal elbow?
A: Yes. The fitting that turns the duct within the wall plane is called a flat elbow in North America and a horizontal elbow by some suppliers. It is the same component.
Q: What angle does the flat elbow turn?
A: 90 degrees. A 45 degree flat bend is available for softer direction changes.
Q: Is it suitable for outdoor walls?
A: Yes. It is moulded from UV-stabilised rigid PVC and matched to the same profile as the straight duct.
