Catnic Cougar Open Back Cavity Wall Standard Duty Lintel – 2400mm (CG70/100) | Supreme Merchants

The Catnic Cougar CG70 Open Back Cavity Wall Standard Duty Lintel – 2400mm (CG70/100) is a premium structural support solution designed for cavity wall openings where reliable strength and thermal performance are required. Engineered as part of Catnic’s trusted CG70/100 series, this lintel is suitable for cavity widths between 70 mm and 85 mm, making it ideal for typical UK residential and light commercial builds.

Manufactured from galvanised steel and finished with a durable black powder coat, the Catnic Cougar lintel offers excellent corrosion resistance and long-term durability on site. Its open-back profile allows continuous masonry construction of both inner and outer leaves, supporting uniform load distribution and helping speed up installation in brick and block cavity walls. The product is supplied with integrated thermal insulation, which helps to reduce cold bridging and improve thermal efficiency of the wall system.

This lintel also incorporates a built-in damp proof course (DPC) and an integral plaster key, reducing the need for separate ancillary components and streamlining finishing work on site. With a 2400 mm span, it is particularly suited to wider openings — such as large windows and patio door configurations — where dependable structural support is essential.

Supreme Merchants supplies this lintel as part of our comprehensive Catnic range, ensuring consistent quality and performance across a wide variety of cavity wall applications.
