Details

The Keystone X/K-90 is a heavy-duty cavity wall lintel engineered to support extreme loads on cavity widths between 90 and 105mm. Ideal for builders and contractors handling demanding structural openings, this lintel combines strength with corrosion protection, making it a dependable choice for serious projects. Please note, the lintel requires lateral restraint and propping during installation for optimal performance.
