The Protecto-Drain by Wallbarn is 100% recyclable and designed to enable a quick and easy installation. This pack contains 3m of Locking Channel Drainage (1m length per channel) and an accessories pack. Channel drains work by collecting surface water from paved or asphalted areas and moving the water away towards an escape route or underground drain pipe. The A15 anti-slip, hardwearing galvanised steel grate maintains structural integrity across the area, so foot traffic and very light vehicles can pass over the drain without issue.

The Protecto-Drain slots in front of your building's entrance or within a paved/asphalted area and provides an unobstructed channel cross-section. Each channel clips together for fast and simple on-site fabrication, and they are easy to cut for areas where a part-metre length is required. All slots and measurement grooves run the whole way through the channel, so you can successfully install sidebars into cut channels.

Questions & Answers


Can you add a 22.5/45 degree curve to this product?


There aren't any corners at that angle available with this product. You could, however, cut the channels to achieve this angle and use silicone sealant to join them back together. 


Hi there, just looking at the wallbarn locking a15 drainage set, is the outlet to the drain only from underneath? I dont have much gradient to play with so was seeing if you can have an end outlet instead? Or an adaptor to change it?


This only has the option to drain from the bottom, the ACO range has a horizontal outlet option.
