Customer Reviews for Master Flow 3-1/4 in. x 10 in. x 7 in. Hood Transition Fan Boot

just installed a new cabinets and appliances, this included a over the range microwave and hood vent ducting. The Master Flow 3-1/4 in. x 10 in. x 7 in. hood transition fan boot fits perfect with the proper offset for installing the duct work for the microwave. The 3-1/4 in. x 10 in. rectangular base is tall enough to allow the vent flap ample room to open and the 7 in. diameter is the right size for connecting to the roof vent.

I was shocked at the installation of the Microwave duct work on the original install. the duct tape was crumbling and a hand cut / bent boot was rigged to work. Not to mention years of grease buildup. This boot made installation look professional and No duct tape used aluminum tape

Worked as advertised

The best part of this product was the extended height of the rectangle end that attaches to the top of my new microwave. The added height allowed the exhaust fan flap room to move freely and provide max airflow. The existing one that was attached to the old microwave was so short that the flap could only open about a 1/3 rd of the way. (no wonder it worked poorly as a range hood)

Fits perfectly. Quality is good.

IT was too large. Had to return it.

Was a perfect fit to install a microwave/exhaust above the stove with this I didn’t need no redusers. It was 7” all the way up to the roof exhaust.

Plenty of room for the microwave oven vent damper to open and close. Builder used a transition for a register which didn’t allow damper to open.

This and some metallic tape did the job ducting my microwave oven to the existing vent to an exterior wall. Works great!

The piece we needed apparently does not exist, but we were able to adapt this universal design to fit our space. So I now have a perfectly working new microwave/range hood. It has changed the efficiency of my kitchen enormously. Thank you very much.

Easy to install, description is well

Just what I needed. It includes a 3" extension of the rectangular element which allows for the damper on the top of a micro-hood to open and close without having to have two pieces as would be necessary otherwise.

Works well to connect standard microwave damper.

I returned this part because I found out that I did not need it. There was nothing wrong with the part.

It works as intended.

This is the only product for this microwave..at Home depot
