We are pleased to bring to your attention a unique boundary wall project we have been involved with. Shown above is a picture of this wall of 4ft above ground height with provision for installing light fixtures. The columns used in the boundary wall have a mild steel pipe at the top for attaching a light fixture and a plastic conduit running along the length through which electrical wires can be introduced. The column also incorporates an electrical box through which the wire can accessed for future repair and maintenance.
I hope you will evaluate this option for your next perimeter wall project
