Carbon grid systems have become so popular in recent years that today 8 or more companies have released products to compete for your attention. Of them all, the Fortress Carbon-Kevlar Strap is demonstrably an industry leader. Fortress is the first company to develop a top-of-wall anchor mechanically bolted to the rim joist for maximum strength, even in older homes.

Their bottom anchor is among the best in the industry. Fastened into the basement floor, the Fortress bottom anchor improves on the American Concrete Institute’s recommendations for anchoring carbon fiber straps. In between top and bottom anchors lie the very best of carbon filaments manufactured today, using the polymer polyacrylonitrile (PAN) method. At the cutting edge of todays science, PAN creates the strongest fibers on earth. Four times stronger than steel! In fact, Fortress Carbon Fiber has a tensile strength of 217,300 psi, compared to a mere 53,000 psi. for steel. Carbon fiber straps are also the lowest profile wall repair solution you can buy. You can paint right over them!
