3-1/4" x 10" x 6'', 6" Diameter Rectangular to Round Duct Galvanized Transition Galvanized Round Transition Microwave Vent Kit for Connecting HVAC Duct Pipe Fittings

It’s good. To be honest I just got it because my dad been wanting one.

Good

Slightly large for most 6” fittings, but otherwise well made. Used for in-ceiling WineMate top-vented wine room AC duct.

Fit so good on my Samsung Over The Range microwave I didn't even need screws.

I bought the 5" item for use with a microwave exhaust. This is a solidly built item, I would buy it again if needed.

just what I wanted

Quality product unfortunately I couldn’t use it for my needs

Pricy but great fit to connect my range hoods

Local hardware stores don’t supply this. Used for our new kitchen and works perfectly

Very well made , heavy steel
