Transitions are custom fabricated from 20 gauge galvanized steel with welded construction. Flanges are not included but will be priced upon request.

Transition Pricing: Price for a Transition is for fitting with square or rectangular end area approximately equal to round end area (within 10%). If Transition is not of equal area, take area of largest end in square inches, convert to a round diameter, and refer to chart for price. If square inch area is in between figures, round to closest diameter.
