Catnic CXL290 Extreme Load Cavity Wall Lintel - 3850mm

The Catnic CXL290 Extreme Load Cavity Wall Lintel at 3850mm is engineered for builders and contractors tackling high-load structural openings in cavity wall construction. This lintel is a reliable choice when strength and durability are paramount, especially suited to cavities between 90-105mm and inner leaf thicknesses of 110-115mm. Please note, a separate flexible DPC must be installed on site as this is not included.

Application

Specifically designed for use in cavity walls with heavy structural loads, the CXL290 lintel provides robust support over wide openings such as large window or door frames. Its heavy-duty construction makes it ideal for commercial and residential projects where reliability under extreme loading conditions is essential. It is commonly used by site managers and structural contractors who require confidence in their lintel performance on serious builds.
