Open Back Cougar Lintels are designed for use in cavity wall construction and come with integrated insulation, plaster key, and a Damp Proof Course (DPC). These lintels are engineered to support the uniform distribution of masonry loads, timber floors, and roof loads, making them suitable for fair-faced inner leaf masonry. They feature duplex corrosion protection, built-in plaster key, built-in DPC, and integral insulation. The lintels are formed from galvanised steel and then powder-coated for durability and ease of use. Cougar open-back profiles are available in standard lengths in increments of 300mm. This specific lintel is designed for cavity walls with a cavity range of 70mm to 85mm, supporting inner leaves from 100mm to 115mm and outer leaves between 100mm and 102mm. It is rated for standard duty applications and is constructed from corrosion-resistant steel, providing reliable load support for domestic and light commercial projects.
