It is a medium-duty lintel, so confirm that the opening span, imposed loads and masonry arrangement fall within the published load and installation limits.
Installation Requirements
- Bed the lintel fully on bricklaying mortar.
- Ensure the inner and outer masonry leaves are suitably tied together.
- For external wall installations, use with a cavity tray. Birtley specifies this requirement for external walls only.
