MCFDT – Floor ducting

Floor duct-EDIT-1530x510 - with keyline

MCFDT floor ducting is designed for use when installing electrical services and incorporates three integral compartment separators for carrying data, power and telecommunication services, which are concealed by a plywood cover.

Manufactured from 22-gauge (0.76mm) hot dipped galvanised mild steel (to BS 2989: 1982 class Z2), the metal tray incorporates return flanges along each side, which support the pre-cut 12mm thick decorative plywood cover (to BS 1203: 1979).

This ensures that the ducting is flush with the finished floor level, whilst also allowing access for inspection and maintenance. The flange upstand may be increased to accommodate the finished floor thickness, thus enabling the visible location of ducting and ease of future access.

The metal dividers within the ducting are linked by location to an integral fixing and earth stud detailed along the tray’s length. Continuous separation of cabling can be maintained by the use of ‘flyovers’ and intersections, which ensure that no wires meet at corners or junctions.

Studs are provided in each length of duct to secure the dividers and connect the earth links which should be provided by the installer and be of adequate cross-sectional area (see current I.E.T Regulations). Larger earth studs can be supplied for 3 phase supply.

When using a concealed outlet box, the base pan of the unit must be fixed to the duct to ensure that a good electrical contact is made for the purpose of earth continuity, which can be achieved by using a floor fixing that passes through the pan and the duct.

Special width and depth sections can be produced for use with any make of socket or concealed outlet systems, including concealed outlet boxes, pyramid boxes and pedestal units. The plywood lid enables sections to be easily cut out on site to accommodate the different options.

A range of accessories are available for the MCFDT range, which include tees, corners, risers to skirting board, and four-way flyovers.
