This Keystone lintel is a galvanised steel unit designed for use in cavity wall construction, suitable for projects requiring extra heavy duty support. Measuring 1500mm in length and 229mm in depth, it is engineered to accommodate a cavity width between 70mm and 85mm, with fitment for inner leaves of 100mm and outer leaves from 125mm to 150mm.
Typically installed above structural openings such as doors or windows, this lintel supports masonry loads across cavity wall builds. Its robust construction makes it suited to demanding residential or commercial developments where wider cavities and heavier loads are a consideration.
