Marshal Tufflex Overview

 

Marshall Tufflex Cornice Trunking Technical Information

 

CORNICE TRUNKING TECHNICAL INFORMATION  

A perimeter cable management system designed to run at ceiling height. With a range of overlapping clip-on fittings and adaptors to enable Marshall-Tufflex Mini-Trunking to be integrated within the system. With a base section specially designed to cater for imperfect walls to ceiling corners.

INSTALLATION

The base should be secured every 500mm by drilling oversize holes in the wall side of the trunking and fastened using round head screws with washers. Avoid over tightening to permit thermal movement. See Material Data page 200 for Thermal Properties.

JOINTS

At each base joint 3mm should be left between each consecutive length of base for expansion and all bends must be mitred to ensure total enclosure of trunking. These mitres are not critical as the fitting covers the bend and overlaps the lid and simply clips on to the base.

ACCESSORIES

These are serviced through a spur using a mini trunking adaptor across the ceiling or down the wall to an appropriate box.
