Details

The Catnic CXL290 Extreme Load Cavity Wall Lintel at 3350mm length is engineered for demanding building projects requiring robust support across cavity walls with 90-105mm widths and inner leaf thicknesses of 110-115mm.

Please note a separate flexible damp proof course (DPC) must be installed on site during construction.

Application

This lintel is ideal for use in masonry cavity walls where significant structural loads need to be supported, such as in commercial developments, housing projects, or heavy-duty extensions.

Proper installation requires lateral restraint and end bearing of at least 200mm to achieve the specified load capacities.
