Channel Drain Junction – Black Grate

Our 4-Way Slotted Junction Unit is the key to creating a truly custom drainage layout for your patio or driveway. While standard channel lengths are great for straight runs, this junction box provides the flexibility to navigate around the corners of a house, frame a square patio, or join multiple drainage lines into one single exit point. Designed for maximum compatibility, each of the four sides features a removable “knock-out” panel, allowing you to connect up to four channels to a single box. This eliminates the need for complex mitred cuts or awkward pipework. The unit comes complete with a high-traction black grate that matches our standard 1-metre channel drains perfectly, ensuring a consistent and professional look across your entire project. Manufactured from high-strength, UV-stable polypropylene, it is built to withstand domestic vehicle traffic (A15 rated) and remains resistant to frost and corrosion. Multi-Directional Versatility: Features four connection points, allowing for 90-degree corners, T-junctions, or 4-way intersections. Seamless Integration: Designed to click directly into our 120mm x 88mm black channel drains for a flush, watertight fit. Simplified Installation: The “knock-out” panels mean no cutting is required to create corners, significantly reducing installation time. Heel-Safe Design: The slotted black grate is designed to be safe for pedestrians and children, preventing trips while maintaining high water intake. Durable & Robust: Rated to A15 load class, making it suitable for driveways, paths, and garage thresholds.
