Built for Cavity Wall Applications

The Catnic CG50/100 is designed for use in cavity wall builds with cavity widths between 50mm and 65mm. Its dimensions make it compatible with inner leaves of 100–115mm and outer leaves of 100–102mm, making it ideal for standard residential walls.
The open back profile simplifies handling and placement on-site. It is suitable for window and door openings where reliable structural support is required.

Rated for Structural Loads

This lintel supports safe working loads up to 15kN at 1200mm span, with options up to 26kN for larger lengths. These ratings meet typical domestic requirements while providing load consistency across cavity spans.

Durable & Protected Finish

The CG50/100 includes a duplex corrosion-resistant coating, making it suitable for damp-prone or exposed environments. Built-in DPC ensures water penetration is minimised along the cavity line.

Insulated and Installation-Ready

Continuous insulation is integrated into the lintel body to help reduce thermal bridging. The integral plaster key allows for a flush interior wall finish after installation.
