Details

The Keystone XCFS/K-70 Extra Heavy Duty Cavity Wall Lintel is engineered to provide robust support for substantial structural openings in cavity walls with widths from 70 to 85mm. Designed for builders, site managers, and contractors handling demanding projects, this lintel delivers dependable performance where load-bearing strength is essential. Please note, all joints must be fully filled with mortar to ensure stability, and lintel propping is advised during installation.

Application

This lintel is primarily used to span openings such as window and door frames within cavity walls, offering extra heavy duty load-bearing capacity for projects requiring exceptional structural support. It’s suitable for use in residential, commercial, and industrial builds where cavity wall thickness falls between 70 and 85mm. Proper mortar bedding on top of the blockwork is vital for even load distribution before laying floor units. Propping the lintel during construction accelerates the build process and ensures safety.
