iPower Flexible 4 Inch 8 Feet Aluminum Ducting Non-Insulated Dryer Vent Hose for HVAC Heating Cooling Ventilation and Exhaust, 2 Clamps Included, Silver, 4 in 8ft New

Great duct and strong for the bathroom exhaust.

Was needing to replace the old vinyl dryer hose with a metal one for a long time. This was easy to install, and does what it is supposed to do. Very satisfied.

Worked well for an inside greenery , very durable

Some customer reviews made me hesitant given the measured diameter of the product. My bathroom fan and wye adapter are about 2 15/16". It is a snug fit, but without too much fuss I was able to fit the hose. This product should work with any item that has an outside diameter of exactly 3" or less. As far as I can tell, this product is identical to most 3" aluminum ducting at time of review (probably re-branded), so quality should similar to other products. This product in particular was the best value. I like that it included two hoses, and thus 2 sets of clamps.

Great product made of thick material. Long and durable. True to size. Very flexible and easy to install. Looks great in black! Perfect for exhaust fans on grow tent!
