Details

The Catnic CXL330 Extreme Load Cavity Wall Lintel at 3400mm is engineered for builders and site managers handling high-load masonry projects. Its robust design and galvanised steel construction make it a dependable choice for supporting cavity walls where heavy structural demands exist. Please note a separate flexible damp-proof course (DPC) must be installed during construction to ensure proper moisture protection.

Application

This lintel is suited for cavity walls with a 130-145mm cavity and an inner leaf thickness of 110-115mm, commonly found in commercial and large-scale residential builds. It supports extreme loads, making it ideal for use above wide openings such as large windows, doors, or structural apertures where standard lintels would not suffice. Contractors appreciate its strength and reliability on serious projects requiring precise load distribution.
