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

The ivory finish matches the warm cream and beige tones widely used on residential walls. Against those surfaces the flat 90-degree elbow looks intentional rather than added on, and the colour-through moulding means the tone never separates from the base material. Ivory also hides light dust better than pure white, which keeps maintenance low on exposed elevations. Together with the matching kit, it completes a fully coordinated 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.
