The wide-span covers WLDR are suitable for WL and WLR 200 wide-span cable trays and protect them from dirt, moisture and UV radiation. They are placed on top of the tray and also have turning bolts for additional attachment. If the covers are to be used outdoors, additional securing brackets to protect against wind are required. In this case, the twist lock alone is not sufficient as a retaining element. The cover is 237 to 637 mm side corresponding to the tray and has a standard length of 3000 mm. We provide components in various materials and surface finishes to ensure that various corrosion protection requirements for different areas of application are met.
