Using the right bag for the job makes everyone’s life easier. Made from a full 4 mil thickness of superior low-density plastic, these 55 - 66 gallon black contractor bags are ready to take on the kind of intense trash that only a construction site can produce. Fill them up with drywall, nails, wood, broken concrete, shattered glass: you name it. The serious puncture-resistance and exceptional resilience of these 4 Mil black contractor bags makes them indispensable on any project. You can use them free-standing, but the strong expanding gusset seal means that they can provide an excellent fit for large drum cans as well.
