Overview
The Heizka 120 Series Straight Section (3A300) is the core channel of the Heizka Fibre Management System – an enclosed plastic raceway designed to protect and route fibre optic patch cords and cable assemblies between network cabinets, optical distribution frames (ODF) and other terminal devices.
With a 120 × 100 mm cross-section and a standard length of 2000 mm, it carries cables horizontally throughout the system and accepts the matching cover and the full range of Heizka 120 series fittings. Smooth internal surfaces and generous bend radii keep fibre within its minimum bend radius, while the high-visibility yellow finish clearly segregates the fibre pathway from copper services.
Key Features
- Enclosed protection – a fully enclosed raceway shields fragile fibre patch cords from compression, dust and accidental damage.
- Bend-radius control – channel and fittings are shaped to maintain the 30 mm minimum bend radius generally specified for fibre.
- Fast installation – connector kits join channel and fittings quickly; no screws are required for normal installation.
- Self-extinguishing plastics – flame-retardant material to UL94-V0, reducing risk to staff, equipment and buildings in a fire.
- Flexible mounting – mounts from walls, ladder rack, ceiling, raised-floor support brackets, floors, or the top of equipment racks and frames.
- Easy to extend – sections and fittings can be added or re-routed later without removing existing fibre or shutting the system down.
- High-visibility yellow – clearly identifies the fibre pathway and keeps it segregated from copper cabling.
A full range of matching fittings (connectors, 90° horizontal elbows, up/down elbows, horizontal and vertical tees, cutting-in tees, horizontal crosses and end-cap kits) is available for the 120 series.
