Description
21mm Plain Back-to-Back Channel | 3 Metre | HDG | 41x42mm | Twin Strut
This 21mm plain back-to-back channel is constructed by welding two 41x21mm plain strut sections. This creates a strong, rigid 41x42mm profile. It is manufactured from 2.5mm thick mild steel and hot dipped galvanised (HDG) for heavy-duty corrosion resistance. Therefore, this unslotted twin channel is ideal for outdoor and exposed high-load support frameworks.

Applications
This plain double 21mm strut channel is ideal for supporting cable containment, mechanical pipework, HVAC installations and structural mounting assemblies in outdoor or exposed environments where a shallower profile than 41mm back-to-back is preferred. The hot dipped galvanised finish gives long-term protection, and the plain face provides a clean finish where slots are not required.
