Q:How do you cut this to make different angles

by|Dec 13, 2015

2 Answers

Answer This Question

A: Thank you for inquiring about MasterFlow Products ... No cutting is required to change the angle for this product. While wearing gloves, grasp the opposing ends and twist in opposite directions. This will allow the joints to turn and then twist to desired angle. Please call Technical Services at 800-211-9612, M-F 8A-5P ET, with any additional questions.

by|Mar 1, 2021

A: You would not. To achieve different angles,, one would entirely fabricate a new elbow.

Worked okay, not true to size though

I found it didn't mate up easily with other 10x3.25 ducting because it's only about 2.75 inches wide despite the description. I was still able to join it to other 10x3.25 ducts using S and drive cleats, but it wasn't as easy as it should have been.

We apologize for any inconvenience. Thank you for your feedback. MasterFlow

I would prefer that the elbow be a smoother curve, however this would require far fabrication, therefore higher cost. The only similar item I found, (Broan), appears identical except for Broan using thinner material, and costing more. This Elbow enabled me to run 10” X 3 1/4” ductwork from the OTR Microwave to the outer vent cap. Which was critical to me, due to our new cabinets having a very small area in which to run exhaust to outside.

Thank you for the feedback. MasterFlow
