PVC 90° Internal Corner – Ø100, RAL

PVC 90° Internal Corner – Ø130, RAL 7016 & RAL 9005

The 90° internal corner joins two gutter runs at a right angle where the building turns inwards – an L-shaped plan, a recessed entrance, the junction between a main roof and a projecting wing. The angle is moulded in, so the joint assembles on site without cutting or mitring, which matters more on internal corners than external ones: they sit in the tightest, most awkward position to work in and take the combined flow from both roof planes.

Moulded in PVC for Ø130 half-round guttering on the 130/90 system, it pairs with the Ø90 downpipe range. The larger 130 mm profile suits bigger roof areas and steeper pitches, where the volume arriving at the eaves in heavy rain exceeds what a smaller gutter will carry. Being plastic, the corner will not corrode, needs no repainting, and moves with the seasonal expansion of a long run rather than straining the joint.
