The Catnic Open Back Cavity Wall Extra Heavy Duty Lintel 3300mm CX90/100 is a high-capacity structural support solution designed for larger openings and demanding cavity wall construction projects. Manufactured from galvanised steel and finished with Catnic’s signature black powder coating, this extra heavy-duty lintel delivers outstanding strength, durability, and long-term corrosion resistance. The open back profile allows continuous masonry construction on both the inner and outer leaf, making installation efficient while ensuring excellent structural performance.

Designed to support uniformly distributed masonry loads, timber floor loads, and roof loads, this lintel incorporates integral insulation, a built-in damp-proof course (DPC), and an integral plaster key. These features help improve thermal efficiency, provide moisture protection, and simplify finishing work. Suitable for fair-faced inner leaf masonry, the CX90/100 lintel is an ideal choice for residential, commercial, and large-scale building projects requiring superior load-bearing capability.
