Concrete Junction Box

Concrete Junction Boxes (also known as J4 Junction Boxes, BT Boxes and Electric Junction Box) provide easy access for cable jointing and maintenance.

This reinforced concrete unit eliminates the need for on-site building.

“The quality of the products are never in question. We’ve always had good experiences working with Moore’s and are very satisfied with the overall service.”
