I had the daunting task of installing heavy aluminum foil in my attic to reduce Florida's extremely hot summer temperatures. Our home is over 30 years old and the yellow pine logs have dried to iron hardness. It is difficult to drive a nail or wire clip into these trusses. I checked out every HD stapler I could find, but most of them didn't get good reviews. I stumbled upon this DeWalt tool by accident and knew right away if it fitted, this was it. I'm a general contractor (30 years old) and supply my crews primarily with DeWalt tools. I bought this stapler and after 10,000 staples (per 5,000 square feet of sheeting) I couldn't be happier. This is an excellent pistol.
