Killeshal Precast Concrete

Junction Boxes

junction boxesWhether you call them Service Chambers, Junction Boxes or even Service Boxes, 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 backfill around it, instant Service Chamber.

Killeshal Precast Services Boxes are manufactured to comply with EN1917:2004 Concrete manholes and inspection chambers unreinforced, steel fibre and reinforced.

We can supply most sizes ex-stock with rapid delivery of our service chambers throughout the UK and the Republic of Ireland usually within 48 hours and as usual we are quite happy to discuss custom requirements.
