Cable tray and conduit supports

Cable tray systems and conduits are designed to provide secure and reliable support for cables, protecting equipment and minimising risks in demanding conditions such as industrial facilities, chemical plants, and offshore platforms. When developing our cable support OBO can offer reliable solutions for systems, three attributes are at the routing and fastening cables securely core of what we do: efficiency, resil- for each of these installation challeng-ience and safety. For ease of installation and accessibility, lay cable and hose in trays instead of pulling it through conduit or raceway. Our range includes PVC and steel trunking, conduit systems and cable tray options meeting current standards. Cable Ladders: Medium-duty, heavy-duty, extra heavy-duty, and ship type cable ladders provide.
