Catnic Cougar CG70 Open Back Cavity Wall Standard Duty Lintel – 1500mm | Supreme Merchants

The Catnic Cougar CG70 Open Back Cavity Wall Standard Duty Lintel – 1500mm (CG70/100) is a reliable structural steel lintel designed to deliver dependable support over door and window openings in cavity wall construction. Engineered for standard duty applications, this lintel is suitable for use in walls with a cavity width of 70mm–85mm and outer/inner leaf masonry thicknesses typical of UK residential and light commercial builds.

Manufactured from galvanised steel and finished with a tough powder coating, the Catnic Cougar lintel offers excellent resistance to corrosion and long-term performance on site. The open-back profile allows continuous build-up of both the inner and outer masonry leaves, ensuring even load distribution and straightforward installation — making it suitable for brickwork, blockwork, and fair-faced inner leaf masonry.

This lintel features an integrated insulation core that helps reduce cold bridging across the cavity wall, contributing to improved thermal performance of the building envelope. It also includes a built-in damp proof course (DPC) and an integral plaster key, which help streamline site installation and finishing, reducing the need for additional materials and labour.

With its 1500mm span, this Catnic Cougar lintel is ideal for medium-sized window openings, standard doorways, and a wide range of typical cavity wall apertures, offering dependable structural support while supporting energy efficiency.
