Details

The Keystone S/K-70 Standard Duty Cavity Wall Lintel is a robust structural support designed specifically for cavity walls with widths from 70mm to 85mm. At 3900mm long, this lintel provides reliable load-bearing capacity for builders, site managers, and contractors working on residential or commercial projects requiring standard duty lintels. Please note that lintels should be propped during installation to ensure stability and speed up construction.

Application

This cavity wall lintel is ideal for forming lintels over window and door openings where the cavity width falls within the specified range. It supports the masonry above openings by distributing loads evenly, especially when a mortar bed is placed on top of the blockwork before floor units are laid. The lintel’s design caters to standard load requirements, making it suitable for many typical build scenarios including extensions, refurbishments, and new builds.
