S/K1502400 KEYSTONE S/K-150 X 2400mm Standard Cavity Wall Lintel
What this product is and who it is for
This is a standard cavity wall lintel manufactured by Keystone. The S/K-150 designation indicates the lintel profile and load-bearing capacity suitable for typical domestic and light commercial applications. The 2400mm length makes it ideal for larger openings or where multiple standard openings need covering. It is designed for builders, structural engineers, and experienced DIY customers undertaking cavity wall construction or renovation work.
- Standard-duty lintel for cavity wall construction
- 2400mm length suitable for substantial openings
- Load-bearing steel construction
- Suitable for new build and renovation projects
Compatibility and sizing
The S/K-150 profile is engineered to work within standard cavity wall systems. Before ordering, confirm that the 2400mm length matches your opening width requirements and that the lintel depth is compatible with your wall construction. Check with your structural engineer or building control if the opening exceeds standard dimensions or if you are unsure about load requirements.
- Verify opening width does not exceed 2400mm
- Confirm lintel depth suits your cavity wall build-up
- Check load requirements with structural engineer for non-standard applications
- Ensure adequate bearing length on both sides of opening
Installation preparation
Before fixing, inspect the lintel for any damage in transit. Ensure the cavity wall is built up to the correct level and that the bearing surfaces on both sides of the opening are level and clean. The lintel must be supported evenly on both sides; uneven bearing will compromise performance. Temporary support may be required during installation until the masonry above is fully built and cured.
- Check lintel for transport damage
- Ensure bearing surfaces are level and free from debris
- Provide equal bearing length on both sides of opening
- Use temporary support during construction if required
- Allow adequate curing time for masonry above lintel
Pack contents and ordering
This product is supplied as a single 2400mm lintel. Measure your opening carefully and allow for proper bearing on both sides before ordering. If your opening is smaller than 2400mm, you may be able to cut the lintel to length, but confirm this is permissible with your structural engineer. Order additional lintels if you have multiple openings.
- Single lintel per pack, 2400mm length
- Measure opening width plus bearing requirements before ordering
- Confirm cutting is acceptable with structural engineer if required
- Order separately for each opening
