The vertical bend carries the trunking over an obstacle in the vertical plane: a gas pipe, a ledge, a roofline step. It keeps the run against the wall instead of letting the duct hang free across the obstruction, which is where a flat elbow would leave the channel unsupported. 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.

Brown answers the most common problem on traditional homes: dark brick, timber cladding and wood-grain fascia boards that no standard colour can match. The fitting sits quietly against these surfaces, and because the tone is mixed into the PVC itself it weathers at the same rate as the rest of the kit. On brick exteriors it is common to run the trunking vertically past a brick course; the brown finish keeps that run discreet without repainting anything on the wall.
Q: How does the vertical bend differ from the vertical elbow?
A: The vertical elbow turns the run from the wall down to the outdoor unit. The vertical bend is used mid-run to step over an obstacle in the vertical plane.
Q: Is it UV stabilised for exterior use?
A: Yes. It is moulded from the same UV-stabilised rigid PVC as the straight duct.
Q: Does it match the duct colour?
A: Yes. Every fitting is produced in the same colour series as the trunking.
