For reliable, everyday domestic drainage requirements, the 4All Drainage Channel (Product Code: 30MHCCH005) is a trade favourite. This 1-metre channel combines a robust polypropylene base with a high-strength black plastic slotted grate, providing a 100% rust-proof solution that is both effective and economical.
Engineered to the A15 EN1433 standard, it’s designed for pedestrian and light traffic areas around the home. The all-plastic construction makes it lightweight, easy to handle on site, and highly resistant to corrosion in any environment.
Key Features:
A15 EN1433 Certified: Suitable for pedestrian traffic, patios, driveways (light domestic use), and garden paths (max 1.5 tonnes).
Corrosion-Free Material: The full polypropylene build ensures long life, making it an excellent choice for coastal areas or high-moisture zones.
Optimal Dimensions: Measures 1000mm (L) x 120mm (W) x 90mm (H), providing good water capacity while remaining relatively shallow.
Simple "Clip-Fit" System: Channels easily clip together end-to-end for rapid installation of long runs.
Easy Maintenance: The grate can be quickly removed for cleaning out silt and debris.
