TerraBloom Flexible 4 Inch Ducting - Black 25 Feet Flex Aluminum Duct with 2 Clamps – 4 Layer HVAC Ventilation Air Hose - Great for Grow Tents, Dryer Rooms, House Vent Register Lines

Lo utilicé para salida de un calentador instantáneo hacia una ventana con un deflecto de 10 cm. Viene en una caja pequeña, compactado como un acordeon, no tiene terminales de adaptación en los extremos para ajustar al calentador y el declecto, es un tanto flexible paro tuve que cortar un poco el cable para ajustarlo. Viene con sus dos abrazaderas. Y adapté unas abrazaderas para tubo pvc de 2 pulgadas, las cuales alargué para que pudieran sostener el tubo que parece un verdadero acordeón y es difícil dejarlo sin soporte. Lo probé una ves y quedó perfecto, buena compra, no le puse 5 estrellas por carecer de las terminales adaptadoras en los extremos, que en la fotografía pareciera tenerlos.

Easy to cut to length with a box cutter and wire cutters for the spiral wire. Very good clamps which use either a slotted screwdriver or Philips. Clamps are very sturdy and hold ducting very securely, much better than the cheap plastic clamps we were using which were always coming off.

Black 4"x25', this is the best value I could find and worth every penny.Good enough to be bought again when the next project comes around.Buy it!

We used this to replace our dryer duct in our crawl space, it was easy to use, install and so far it has held up very well! Thank you.

This is better than average quality. Nice hose. would buy again.
