Drill holes into the wall at your marked support points. Insert wall anchors (expansion bolts for concrete). Option B: Ceiling Suspension (Trapeze or C-Hanger) Drill holes into the structural. 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. Our cable support. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require. ngs, etc. Structural building members should never be cut, and cable trays should not be installed in hoist way or where subject to physical. Scope :- This specification covers the following major activities; - Fabrication and installation of Mild Steel (MS) support structure for Galvanized Iron (GI) Cable tray. - Installation of perforated GI Cable tray of size 300 x 50 mm at height ~12 meter on wall and existing metal support structure. The screw-on cable tray systems fulfil the requirements of “IEC 61537:2006 – Cable management ‒ Cable tray systems and cable ladder systems” for the low voltage area.
