Details

The Catnic CXL310 Extreme Load Cavity Wall Lintel at 5450mm is engineered for demanding structural applications where heavy loads are expected. Perfect for builders, contractors, and site managers working on cavity walls between 110 and 125mm, this lintel offers a reliable and durable solution backed by strong technical specifications. Please note, the lintel is supplied without a built-in DPC, so a separate flexible DPC must be fitted on site.

Application

This lintel is suited for heavy-duty cavity wall constructions, supporting brickwork or blockwork over large openings such as commercial doorways or substantial window apertures. It is essential for projects requiring extreme load-bearing capacity, provided it is installed with appropriate lateral restraint and minimum 200mm end bearing. The lintel is commonly used by contractors and developers on serious building projects where structural integrity is critical.
