Trash chutes help take out dust and minimize the danger of flying debris as well as costly jobsite clean-up. Ours are made of high quality UV-resistant material and these chutes are light-weight and can be stored flat to save space. Each chute section is 30″ diameter, 48″ in length. Since each section tapers into the next section, calculate approximately 44″ per section to determine number of chutes needed. Chutes lay flat for easy storage or transportation.
