Height 50mm open bottomed drainage channels, manufactured from recycled polymers, with hot dip galvanised mesh. Used to prevent surface water accumulation, at terraces or adjacent to walls. Drainage channel dimensions are (L × W) 1000mm × 150mm. Weight 3,75 kg.
The RNF roof channels should be positioned along terrace doors, low windows, and at terrace-wall junctions. Their use should be considered especially where there are large surface areas, as these also collect a substantial amount of rainwater.
