Contractor bags are a breed apart, and this one goes even further, offering extreme strength. More than a match for any construction site, these 55 - 60 gallon black bags can take a beating and come back for more. This bag is as heavy duty as they come. The 6 mil thickness of low-density resin can expand and twist without tearing, no matter what. It will hold up against nails, shattered glass, lumber, and bricks without the risk of punctures. The gusset seal gives it a comfortable fit in large drum cans, but this bag also performs well freestanding. Buy contractor bags in bulk and save BIG. Made in the USA to the very highest quality standards.
