Anthracite Composite Internal Corner Trim 3.6m — Series 1 Cladding

Create clean, professional internal corners on your composite cladding installation with our Anthracite Composite Internal Corner Trim. Designed for use with Series 1 cladding boards, this trim neatly conceals the joint where two boards meet at an internal angle — delivering a seamless, colour-matched finish that elevates the overall look of your project.

Made from recycled wood and plastic composite, this trim is built for long-term outdoor use. It will not rot, warp, or splinter, and requires no painting, staining, or sealing — making it a genuinely low-maintenance finishing solution for exterior cladding projects.

The cool anthracite finish provides a sleek, contemporary edge that complements the Series 1 cladding range, adding a crisp, defined line to garden buildings, boundary walls, and exterior structures. Can be fixed using screws or outdoor adhesive for straightforward installation.
