Customer Reviews for Master Flow 4 in. 90 Deg. Round Adjustable Elbow

Great way to change direction of your 4 inch aluminum ducting

This quality was good but I could only get it to approximately 90 degrees, 34 minutes 14 seconds of angle. I did not have instruments to measure this, only judged it by eye, and in my application it functioned just fine, but....

Worked perfectly. My clients dryer was ventilated with the wrong type of ventilation hose causing the dryer to overheat and short cycle. They’d have to run the dryer several times to dry their clothes. This was part of the fix.

Solid, much better than the light gauge alternative

Worked just as advertised.

Meet our expectations

Flexible and robust unit. I was surprised at what angle I could achieve with a pair of these.

This adjustable elbow was of good quality and design. It allowed for an abrupt change of direction for my dryer vent hose without the concern of distorting the hose. Many degrees of angle are provide by this elbow.
