Collingwood Ground Light Installation Tube - 56mm Diameter

Get the Groundwork Right First

Ground lights need a clean, stable hole to sit in once the paving, concrete or lawn around them is finished. This aluminium tube is what makes that possible. You set it in place while the groundworks are still being done, so the ground light itself has a ready made recess to drop into later, rather than a hole cut or cored after the fact.

The 56mm Diameter Version

This is the TUBE/50, sized to a 56mm internal diameter for Collingwood's smaller ground light bodies. It has a hole cut into the side wall near the base for the cable to exit sideways, rather than straight up through the bottom of the tube. Check the cutout and depth needed for your specific ground light before you order, so the tube matches the fitting going into it.

How It Works

• The tube is set into wet concrete, compacted sand or firmed soil before the surface finish goes down
• Once everything has set, the ground light body drops straight into the tube
• The side cut hole lets the supply cable run out to one side, keeping it clear of the base of the fitting
• Lining the hole this way stops the surrounding concrete, paving or soil crumbling into the recess over time

Where It's Used

This tube earns its keep on any job where the ground light goes in after the hard landscaping. Driveways, patios, paths and steps are the usual places, along with lawns and borders where a ground light will be recessed once turf or planting goes back in. It's especially useful on new build or renovation projects, where the groundworks and the electrical fit out happen weeks apart.
