Stay-Tuff 2" double-barbed staples are known for their ability to drive straight into the post because the ends of the staples are even, and razor sharp. The double-barbed edges help ensure that the staple will hold strong and tight. They are manufactured from heavy-duty 8 gauge wire, which is stronger than the other fence staples on the market, and they are made from class 3 wire so they will be durable for the life of your fence. 2 lb staples come in a reusable high-quality clear plastic jar, with screw on lid. Staples are also available in 1-3/4", 1-1/2", and 1-1/4" lengths in 2 lb, 10 lb, and 40 lb plastic containers. All Stay-Tuff staples are proudly made in the U.S.A.
