Key Design Features
The unit is supplied with four solid sides and any of them can be removed to let water flow into or through it. Removing two turns a run through 90 degrees, and removing three forms a T-junction. Taking out the internal base opens a vertical connection onto 110mm diameter PVC-U underground pipe, and the same opening takes a rainwater downpipe.
Benefits
- One part covers corners, T-junctions, downpipe connections and outlets, so there is less to order.
- Sides are removed on site, so a single unit suits several layouts.
- Connects vertically onto 110mm PVC-U pipe without an extra fitting.
- At 0.20kg it is light to position while a run is being set out.
- Black plastic grating matches the standard HexDrain channel grating.
Applications
Use the ACO 19559 wherever a HexDrain run turns a corner, meets another run, takes a downpipe or needs to drop into underground pipework. It is the fitting to reach for on domestic driveways, patios and paths laid with HexDrain channel.
