The Luxair 100mm x 60mm flat ducting 90° horizontal elbow connector
...joins two lengths of 100mm x 60mm flat rectangular ducting at a right angle in the horizontal plane — turning the duct run left or right along the top of wall cabinets, across a ceiling void, or within a wall chase without changing the vertical height of the run. Self-sealing push fit, and the smooth interior bore maintains airflow efficiency through the bend.
Horizontal vs Vertical — Which Elbow Do You Need?
This is the question that causes the most wrong purchases in the flat ducting range. A horizontal elbow turns the duct run left or right — the duct stays at the same height throughout the bend, travelling along a flat surface like a cabinet top or ceiling line. A vertical elbow turns the duct run upward or downward — used when the run needs to change floor level, drop into a cabinet void, or rise up through a ceiling. If your ducting run travels along the top of your kitchen wall cabinets and needs to turn a corner at the end — left or right — this is the correct fitting. If your run needs to go up or down at any point, use the 100mm x 60mm 90° Vertical Elbow instead.
Where This Fitting Is Used in a Typical Installation
The most common scenario for this elbow is a flat ducting run travelling horizontally along the top of kitchen wall cabinets that needs to turn a corner — for example, when the hood is on one wall but the external vent is on an adjacent wall. The flat duct runs straight from the adaptor at the hood outlet along the cabinet top, hits this horizontal elbow at the corner, turns 90°, and continues along the next run of cabinets toward the external wall vent. Two horizontal elbows back-to-back can also be used to create a U-shaped offset where structural elements or pipework block a straight run.
Self-Sealing Push Fit — No Tape at Rigid Joints
Both ends of this elbow are push fit and self-sealing against 100mm x 60mm flat ducting pipe and matching fittings — no ducting tape, sealant, or clips required at any rigid-to-rigid joint in the run. Tape is only needed when the run transitions to flexible aluminium or plastic flexible hose at any point. The smooth interior bore through the bend minimizes airflow turbulence compared to sharper or poorly fitted junctions, maintaining extraction efficiency through the corner.

Is 100mm x 60mm the Right Size for Your Hood?
100mm x 60mm flat ducting is the equivalent airflow cross-section to 100mm round ducting and suits cooker hood motors rated below 450 m³/hr. For higher-rated motors use larger ducting throughout the entire run:
- Below 450 m³/hr → 100mm round or 100mm x 60mm flat ducting
- 450–750 m³/hr → 125mm or 150mm round, or 220mm x 90mm flat channel
- 750–2000 m³/hr → 150mm or 200mm round ducting
