Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust

除湿機ほ排熱用ホースの為購入。 size 100Φ 、ちょっと大きめでも接続できた。中々 100Φで長さ6mを越えるものがなく、良い商品に巡り逢いました。 ホースの構造もしっかりしていて、かなり伸ばせて使用できるため重宝しています。

Todo bien, gracias

Lo utilizo para sacar aire por medio de un extractor, me parece que tiene una excelente longitud para su precio, excelente!

I went searching for a more 'permanent' vent product for use in venting bathroom exhaust fans to the outside. I was skeptical to say. However, upon arrival it was clear this product WAS indeed several levels of quality above the typical aluminum foil exhaust duct. As such, I was pleasantly surprised and impressed by the quality. So, if you are looking for something to go 'behind the wall' or 'above the ceiling', this should do the trick. As a 'flag' to denote this as a legitimate comment ~ go Bengals and may we please find an offensive line!

First thing first, the build is solid, and it seems to insulate well. It fit great and can in some really cool packaging. HOWEVER, I am returning this because the ends of the tube don’t have a clear space for putting in the ring tighteners. The ends are simply just cut, which means you have the spiral wiring going all the way to the end, which your ring tightener will have to go over, thus not a proper seal. If you are a stickler for having flawless insulation on the ends, I would probably get something else.
