|Cavity floor trunking is used to supply power, telephone
and data services to remote cavity floor boxes.
Supplied in standard 3 metre lengths in two, three
or four compartment options, each length is supplied complete with fast
fix cover and coupler.
Services are accessed via header boxes which may
be located in the body of the trunking. When using this method the cavity
depth from the slab to the underside of the tile must not be less than
90mm. Should the cavity be less than 90mm the services are accessed
through 20mm knockouts, pre-punched in the trunking side wall at 600mm
centres, one per compartment. When using this method a transfer unit
is fitted to allow easy access from the central compartments.
