Details

The Keystone BOX/K-100 Solid Wall Box Lintel, measuring 4350mm in length, is engineered for builders and site managers working with solid walls between 100mm and 215mm thick. This standard duty lintel is a dependable choice for supporting internal openings, offering robust load-bearing capacity throughout masonry construction.

Application

Ideal for use in solid wall builds where internal openings such as doors or windows require reliable support. The box lintel design carries the full load of wet masonry as soon as it is laid, making it suitable for efficient, continuous brickwork or blockwork. It is essential to provide a minimum end bearing of 150mm on each side, with the lintel bedded in mortar for proper load transfer. Propping during installation is recommended to maintain structural integrity and accelerate build times.
