The Keystone Timber Frame Lintel TK-50 is a high-performance structural component designed for timber frame construction with a cavity width of 50-65mm. Engineered to meet rigorous thermal performance and fire safety standards, this lintel ensures robust support for outer brickwork over openings. Its pre-galvanized steel construction offers exceptional durability and corrosion resistance, while the zinc grey finish adds a professional touch. For optimal performance, use in conjunction with lateral restraint clips and a tight-fitting timber batten to prevent twisting. Propping the lintel can also expedite the construction process.
