Underfloor Trunking

Underfloor trunking is used to supply power,telephone and data services within office accommodation with a minimum screed depth of 70mm, to accept a maximum system depth of 63mm.

Supplied in standard 2 metre lengths in two or three compartment options, each length is supplied complete with fixing clamp and connector.

A predetermined grid design incorporating the position of the trunking, junction and service boxes is required for direct fixing to the constructional slab prior to screed being laid. During screening both junction and service boxes may be fitted with disposable closure plates to prevent ingress to the system. Following the screed being laid, the closure plate is removed and the top assembly fitted. The top assembly is fully adjustable to allow for screed height adjustment.
