Rectangular duct branch, 90°: flat patterns
A rectangular branch leaves a rectangular trunk square, the height the same throughout, as on a tee or a take-off. It is built from five plates: the top and the bottom cut to the T of the plan, the trunk's back, and two sides that run from the trunk round the corner up the branch.
A rectangular branch square off a rectangular trunk, of one height; five plates.
