DuraPlus Wall Strap

Wall Straps are designed for both interior and exterior chimney installations, providing vital support and stabilization while maintaining a safe 2” clearance. For exterior installations, wall straps must be installed every 4 feet to ensure proper support and safety. Available in 10" and 12" outside diameters for 6” and 8” inner diameters, these wall straps are an essential component for secure and compliant chimney systems. Options for stainless steel or galvanized outer wall. Additional DuraPlus Info: DuraPlus is engineered to maintain a cooler exterior while promoting a hotter draft inside, enhancing stove efficiency and ensuring a fire-safe design that safeguards both the chimney and the surrounding structure. This triple-wall chimney features two layers of insulation: a ceramic blanket and an air gap. The ceramic blanket insulation is securely positioned, preventing the hot spots often caused by loose-fill insulation types. In the event of a creosote fire, the compressible insulation allows the chimney liner to expand outward radially. Built to withstand continuous operation at 1000°F flue gas temperatures, DuraPlus meets the rigorous UL standards, including one hour at 1400°F and three ten-minute chimney fire tests at 2100°F.
