Codecom Marker Posts are a robust, Australian-conditions-ready solution for identifying and protecting directly buried optical fibre cable installations. Constructed from hot dipped galvanised steel pipe with a powder coated safety yellow aluminium extrusion, each post stands 1.5 metres above ground once installed and is clearly visible along the cable route. The top plate displays all critical cable information — including depth, distance, route direction, and a unique post identifier — while the reverse warning sign references Dial Before You Dig (Free Call 1100) to safeguard against third-party excavation damage. Three ground spike lengths accommodate rocky, normal, and sandy soil conditions, and all hardware uses vandal-proof fasteners throughout.

Features and Applications

• Hot dipped galvanised 50NB XL steel pipe (60.30mm O.D. × 1.30m) with 2.00mm wall thickness — heavier duty than the competitor standard of 1.60mm
• Powder coated safety yellow aluminium extrusion (300mm × 112mm sides) with screen-printed information panels sealed with a protective coating
• 2.50mm laser cut aluminium top cap, screen printed and sealed with protective coating
• CD-Spike600 ground anchor (3.0mm thick × 600mm fins), hot dipped galvanised, tapered to fit 60.30mm post
• Three spike lengths available — 450mm for rocky soil, 600mm for normal soil, 750mm for sandy soil — to suit varying ground conditions
• Vandal-proof Pentagular Tek screws secure post to spike; vandal-proof tri-lobe Tek screws secure top cap to extrusion
• Top plate displays cable depth, distance to cable, route direction, post ID, and Dial Before You Dig reference (Free Call 1100)
• Reverse warning sign provides prominent underground optical fibre cable alert for excavation safety compliance
• Posts stamped with unique identifiers; joint posts prefixed with ‘J’ for clear route documentation
• Suitable for directly buried fibre cable routes in telecommunications, utilities, mining, and civil infrastructure applications
• Must be installed no further than 250 metres apart, maintaining line of sight along the cable route
• Installed at cable deviations greater than 0.6 metres, direction changes greater than 20 degrees, and at all pits, manholes, and joints
