Overview
The Heizka Cutting-in Tee creates a 90° horizontal branch from anywhere along an existing straight run – without cutting the run into two sections and without disturbing the fibre already installed in it.
It is the fitting to use when a pathway has to be extended after commissioning: the tee clamps onto the side of the channel, so a new spur can be added to a live system with minimal disruption.
Key Features
- Branches off an existing run without cutting it – no need to remove installed fibre.
- Ideal for adding pathways to a system already in service.
- Available in the 120, 240 and 600 mm series.
- Bend-radius control – the moulded profile keeps fibre patch cords within their minimum bend radius through the fitting.
- Self-extinguishing plastics – flame-retardant material to UL94-V0.
- Toolless or low-tool assembly – joins to channel and other fittings with the matching Heizka connector kits.
- High-visibility yellow – keeps the fibre pathway clearly segregated from copper services.
- Matching snap-on cover – the fitting is fully enclosed once the cover is fitted (where a cover is listed).
