Details

The Keystone X/K-70 WOL 1800mm lintel is a specialist heavy-duty cavity wall lintel designed for builders, contractors, and site managers working on structurally demanding projects. It supports wide outer leaf cavity walls with cavity widths between 70 and 85mm, making it ideal for robust blockwork applications where extreme loading conditions apply. Please note that the lintel must be laterally restrained during installation to achieve the stated load capacities.

Application

This lintel is typically used to span openings in cavity walls where the outer leaf measures between 125 and 150mm thick, such as in commercial or high-spec residential developments. Its extreme duty rating ensures it can safely carry heavy loads above large window and door openings. For best practice and to expedite construction timelines, it is recommended that lintels are propped temporarily during installation to maintain structural integrity.
