TJ’s Tip:
When installing this quad box, ensure you knock out only the required inlets/outlets using a sharp blade or hole saw. This ensures the remaining connections stay watertight. Remember to bed the entire unit in a concrete or mortar base to provide essential stability and support for the A15 load rating.
