Made for Cavity Strength


Catnic CG110/100 125mm Cavity Wall Lintel is engineered for wall builds using wider cavity configurations. With support for cavity widths between 110mm and 125mm, it accommodates thin joint blockwork and maintains strong structural support across inner and outer leaf assemblies.

Durable and Moisture Resistant


The galvanised and powder-coated finish protects the lintel from corrosion and wear. A built-in DPC prevents water ingress, while the staggered slot plaster key enhances adhesion and insulation performance along internal surfaces.

Load Rated and Verified


This lintel offers safe working loads from 12kN to 26kN depending on length. Designed for standard duty applications, it supports distributed masonry, timber floor, and roof loads with consistent performance across all sizes.

Range and Fit


Available in standard lengths from 900mm to 3000mm, this lintel provides options for domestic and commercial projects. Nominal heights vary from 147mm to 225mm to match construction needs. Product weights span from 6.43kg to 43.16kg.
