For years, the standard packaging for insect screening was rolls of 100 lineal feet. Retailers cut off whatever length was required by a customer. While many retailers still carry both aluminum and fiberglass in 100' rolls, more are offering screening in precut and individual packaged rolls. Precut rolls are 84" in length, which is enough to repair most windows and doors. Each roll is packaged for the do-it-yourselfer with complete instructions. Most manufacturers also offer precut and packaged rolls in 25' lengths. Several new racks are currently available for measuring and cutting required amounts of screening material off large 100' rolls. These racks are available with counters that measure the screen as you pull it across a roller wheel and also with a cutting table to conveniently cut the screen once it is measured. Rack systems are also available for displaying the precut rolls.
