Setup, Compatibility & Care

Preparation: Ensure the cavity wall is constructed to the correct dimensions (90mm-105mm). Check the opening size and select the appropriate length of lintel.
Installation: Place the lintel over the opening, ensuring a minimum 150mm end bearing on both sides. Use appropriate mortar to bed the lintel, ensuring it is level.
Leaf Alignment: The lintel is designed to support specific inner and outer leaf dimensions; verify these match your construction. Both inner and outer leaves can be raised simultaneously.
Block Course: Lay a block course prior to installing flooring or roof elements to enhance structural performance.
Compatibility: This lintel is compatible with standard cavity wall construction methods. It is designed to work with inner leaves from 100mm to 115mm and outer leaves from 100mm to 102mm.
Care: No specific ongoing maintenance is required due to its galvanised steel construction. However, it's recommended to inspect the lintel during construction and after completion to ensure it is correctly installed and free from damage. Handle with care to avoid damaging the protective coating.
