Flanged Y Branch 12ga

Nordfab duct branches in Y shape (sometimes called “true wyes”) are standard 60º between legs, optional 90º.

12 gauge steel construction adds extra durability.

Standard with our rotational Angle Flange (AFL) ends.

When ordering specify A, B, C.Both B & C each must be at least 50% of A, with B or C being at least 80% of the opposite leg. Use the following formula to determine length: L = A + 4”.

Galvanized steel construction
Available with 60° or 90° angle
Additional branch gauges available: standard 22 and 20, 18, 16, 14, and 10
