Catnic Cougar Open Back Cavity Wall Standard Duty Lintel – 2100mm (CG70/100) | Supreme Merchants

The Catnic Cougar CG70 Open Back Cavity Wall Standard Duty Lintel – 2100mm (CG70/100) is a high-quality structural steel lintel engineered to provide dependable support over wider openings in cavity wall construction. Designed for cavity widths between 70mm and 100mm, this lintel is part of Catnic’s standard duty Cougar range, offering a robust and thermally effective solution for door and window apertures in both residential and light commercial projects.

Manufactured from galvanised steel with a durable powder-coated finish, the lintel delivers excellent corrosion resistance and long-term performance on site. Its open-back profile allows continuous masonry build-up of both the inner and outer leaves, ensuring consistent load distribution while simplifying installation.

An integrated thermal insulation core runs along the full length of the lintel, helping to reduce cold bridging across the cavity wall and improving the overall energy performance of the building envelope. Built-in features such as a damp proof course (DPC) and an integral plaster key further streamline installation and finishing, reducing the need for additional materials.

With a span of 2100mm, this Catnic Cougar lintel is particularly suitable for larger window openings, substantial doorway spans, and medium-wide cavity wall apertures where reliable structural support and thermal performance are essential. As part of the CG70/100 standard duty range, it supports uniform masonry loads as well as common timber floor and roof loads typical in standard builds.

Supreme Merchants offers this lintel as part of a comprehensive range of Catnic lintel sizes, enabling consistent specification and performance across multiple openings in a project.
