Black 5 Grid Seamless Corner Trim for Composite Slat Wall Panels – WPC Continuous Corner Finishing Piece

Black 5 Grid Seamless Corner Trim for Composite Slat Wall Panels – WPC Continuous Corner Finishing Piece

Black exteriors demand precision — and nothing breaks the look faster than a raw or poorly finished corner. This Black 5 Grid Seamless Corner Trim is designed to carry the bold, matte black aesthetic of your composite slat wall panels continuously around every outside corner, wrapping the slat pattern so it reads as one uninterrupted surface from face to face. At 106" long, a single piece handles the full height of most wall installations without any mid-run joints. Sharp lines. Seamless result. Exactly what a high-contrast black exterior calls for.

Installation is clean and uncomplicated — apply adhesive to the back of the trim, align it to the corner, press into place, and hold until set. The seamless profile is matched to the 1" slat spacing and black finish of the 5 Grid panel line, so the corner transition is invisible rather than obvious. Works on outside corners wherever your slat wall panels meet an edge or turn. No complex cuts needed for a standard 90° corner.

Manufactured from WPC (Wood-Plastic Composite) and finished in matte black to match the Black 5 Grid panel system, this trim is built for long-term exterior exposure. UV-stable, moisture-resistant, and warp-resistant — the finish holds its deep, consistent black tone alongside your panels year after year with no painting, no touch-ups, and no maintenance. A seamless corner that stays looking intentional.
