Metallic cable support duct - uses open U=shaped duct support on square section tubes

摘要

The cable support duct system uses two square section tubes, are at a certain distance from each other and parallel to each other. The system uses a certain number of U-shaped transverse supports and a certain number of open end channel pieces. The channel pieces fit into the transverse supports, which are soldered and welded to the square section tubes. Sections of the duct system arefitted together using square section pieces slightly smaller than the tube sections. These pieces have a hole in them. A pin passes through a hole in the square section tubes and into the hole of the fixing piece.
