Teak A1 5 Grid 90° Corner Trim for Composite Siding Slat Panels – WPC Right Angle Finishing Piece

Teak A1 5 Grid 90° Corner Trim for Composite Siding Slat Panels – WPC Right Angle Finishing Piece

A clean slat wall installation lives or dies in the details — and raw, unfinished edges are the fastest way to undermine an otherwise great project. This Weathered Teak 90° Corner Trim is engineered specifically for 1" Wide Exterior Slat Wall Panels, giving you a polished right angle transition wherever your panels meet a corner, doorway, window surround, or wall edge. At 106" long, a single piece covers the full height of most installations in one run — no awkward joints, no patchwork terminations. Just a clean, continuous finish from top to bottom.

Installation is glue-down and straightforward. Apply adhesive to the back of the trim, press it firmly into the corner or edge position, and hold until set. The right angle profile sits flush against both faces of the corner, covering any exposed panel ends cleanly. Works on outside corners, door and window openings, the top and bottom of panel runs, and anywhere else you need a finished termination point. One trim piece. Every edge handled.

Made from WPC (Wood-Plastic Composite) and matched to the Weathered Teak finish of our exterior slat panels, this trim holds up to the same outdoor conditions your panels face every day. Moisture-resistant, UV-stable, and warp-resistant — the warm, weathered teak tone stays consistent alongside your slat wall without fading, cracking, or requiring any maintenance. Everything matched. Everything finished. Nothing left raw.
