Trash Chutes help eliminate dust and the danger of flying debris as well as costly jobsite clean-up. High quality UV-resistant material, these trash chutes are durable light-weight and can be stored flat to save space. Trash chute section is 30″diameter, 4′ in height. Each section tapers into the next section, calculate approximately 4’per section to determine number of chutes needed. Trash Chutes lay flat for easy storage or transportation. Note: OSHA Regulation 1926.252 requires the use of an enclosed chute whenever materials are dropped more than 20 feet to any point lying outside the exterior walls of a building.
