Rectangular duct elbow, mitred: flat patterns
A rectangular duct turns in plan at one mitred corner, at whatever angle the run needs. The top and the bottom are cut to the plan, the mitre halving the turn; the two sides are flat sheets bent once at the mitre.
A rectangular duct turning in plan at one mitred corner, at any angle, the height the same all along; four plates.
Sizes you enter
- Width (W): Across the duct, seen from above, on the surface chosen under Sheet.
- Height (H): Across the duct, seen from the front, the same all along.
- Bend angle (A): How far the duct turns, more than 0° and less than 180°.
- First leg (E1): From the first end to the mitre, on the centre line.
- Second leg (E2): From the mitre to the second end, on the centre line.
What you get
The exact flat pattern of the part, worked out for the sheet thickness measured on the inside, the mean or the outside, with numbered press lines, the part in 3D, its weight and cutting length, and a DXF for laser, plasma or waterjet cutting (STEP as well).
