This is a heavy duty galvanised steel cavity lintel from Keystone Lintels Ltd, designed for installation in cavity wall constructions. Measuring 900mm in length, it is suitable for applications where space and opening sizes are limited, offering reliable structural support over door or window openings.
Typically used in brick or block cavity walls, this lintel accommodates cavities between 50mm and 65mm and is compatible with both inner and outer leaf wall sizes. It is fixed in place during the building process to support the weight above structural openings, commonly in residential or light commercial builds.
