Details

The Keystone BOX/K-200 Solid Wall Box Lintel, measuring 3450mm in length, is engineered for builders and contractors working with solid masonry walls ranging from 100 to 215mm thick. This standard duty lintel reliably supports internal openings, carrying the full load of wet masonry as soon as it is installed, making it an efficient choice for structural openings on site. Please note, lintels require correct bedding and propping for optimum performance.

Application

Specifically designed for solid wall construction, the BOX/K-200 lintel suits internal wall openings such as doorways and windows where a strong, stable support is essential. Its perforated surface ensures a strong bond with plaster, improving finish quality and durability. Builders should ensure a minimum end bearing of 150mm on each side, bedding the lintel firmly in mortar. Propping during the construction phase is recommended to speed up the build process and maintain safety standards.
