Flanged In Cut 45°

Flanged In Cut 45°

Flanged In Cut duct fittings are used to add ducting into existing lines of industrial ductwork. In-cuts are also known as “saddle taps”.

In-cuts are standard 30° or optional 45° (45° item numbers shown below).

Provided with industry-standard Angle Flanges on both ends, the flanges are retained via a vanstone lip so that bolt holes can easily be aligned with those on existing flanged connections.

  • When ordering In Cuts, specify A and C diameters.
  • Saddle length and width = 3" all directions from Branch Tube C.
  • Available in galvanized steel and 304SS (as shown below) or optional 316SS or carbon steel
  • Available with QF ends in diameters up to 24", flanged diameters up to 72", and other end types
  • Other material gauges available include 18, 16, 14, 12 and 10
  • Flange gaskets available

Contact Nordfab or your local Nordfab dealer for assistance with optional end types, larger sizes, and material / gauge options.
