Details

The Keystone CFS/K-90 Extra Heavy Duty Cavity Wall Lintel at 3900mm length is specifically engineered for trade professionals working on cavity walls with widths between 90 and 105mm. Its robust construction makes it ideal for demanding load-bearing applications, giving site managers and builders confidence in structural integrity. Please note that all joints must be fully mortared and the lintel should be propped during installation for optimal performance.

Application

This lintel is designed for supporting large openings such as windows and doors in cavity walls where an extra heavy duty load capacity is required.
