We’re proud to offer these specialty garbage bags which measure a full 4.0 Mil thick. These bruisers sit confidently in the top weight class, ready to take on anything that comes their way. Contractor garbage bags are as important as any other tool on a construction site, keeping things organized, neat, and most of all, safe. They can be filled to the brim with super heavy, super rough trash, keeping all that stuff out from underfoot.
