QF Double Branch 18ga

QF Double Branch 18ga

QF Double Branches are standard with QF rolled ends, allowing quick connections with other QF ductwork.

18 gauge material construction adds extra durability.

  • When ordering, specify material; gauge (if nonstandard); dimensions A, B, C, and D; end styles if not all QF; and angle (standard 30° or optional 45°).
  • (A - C) ≥ (C-B) and (C) ≥ (D). Use formula above to determine if a reducer is needed at C or D.
  • Length = C X 2 + 9"
  • Available with flanged ends in diameters up to 72", and other various end types
  • Available with 30° or 45° angle
  • Other available gauges include standard 22 and 20, 16, 14, 12 and 10
