The ST95084 TerraKing Pro Leaf Bag is the bag for those who are serious about leaf cleanup. Made with polyester and a nylon-bottom, this is the ultimate heavy-duty bag for those who need to pick up leaves on rough terrain. If you have a two-bag material collection system, this is the perfect bag for you. The ST95084 TerraKing Pro Bag offers a maximum bag opening circumference of 120 inches, with 54-Cu. Ft. Capacity. After removing your collection system's existing bags, you simply drape the leaf bag's opening over the hood, pull the debris flap over the front, and tighten the two cord locks to secure it in place. While in use, the abrasion-resistant polyester ensures that you're investing in a durable leaf-collecting solution for use season after season and a nylon-bottom gives you even more protection against rough terrain. Additionally, our design promotes airflow while trapping dust and debris, which results in less mess while you collect your leaves. All of our leaf bags are proudly made in the USA. This bag requires a material collection system; however, a material collection system is NOT included in the purchase of this bag
