Overview
The Heizka Up and Down Elbows raise or lower a horizontal run of fibre raceway to a different level. Used as a pair, an up elbow and a down elbow step the pathway over an obstruction or move it between two heights while keeping the fibre enclosed and within its bend radius.
The 60 mm series uses 90° up and down elbows; the 120, 240 and 360 mm series use 45° up and down elbows for a gentler transition.
Key Features
- Changes the level of a horizontal run without cutting or re-terminating fibre.
- 90° up/down elbows for the 60 series; 45° up/down elbows for the 120, 240 and 360 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).
