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 black, moulded from the same colour-through PVC as the black kit, so joints and corners stay invisible on the wall.

For contemporary facades and commercial fit-outs, black is the practical choice. It pairs naturally with dark cladding, grey concrete and black-framed glazing, and it hides road dust and urban grime far better than lighter finishes. The flat 90-degree elbow is moulded in our own factory from colour-through PVC, so the surface keeps its depth of colour through years of sun and rain. It is the finish we recommend wherever the design brief calls for the line set to look like architecture, not service pipework.
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.
