Details

The Keystone X/K-50 Extreme Duty cavity wall lintel is a specialist structural support designed for builders and site managers working on heavy-duty projects. Measuring 4200mm in length, it is ideal for openings in cavity walls with widths between 50 and 65mm. Please note that the lintel requires lateral restraint and must be propped during installation to perform as specified.
