Concrete Service Boxes

concrete service boxesjunction boxesWhether you call them Concrete Service Boxes, Junction Boxes or even Service Chambers, here is the solution to a common site problem. Simply pour a base, install the box and when the required cables have been installed, place the lid on the box and back-fill around it, instant Concrete Service Boxes.

KPC Concrete Services Boxes are manufactured to comply with EN1917:2002 / AC:2008 Concrete manholes and inspection chambers unreinforced, steel fibre and reinforced.
