Details

The Keystone HDBOX/K-150 is a heavy duty box lintel specifically designed for 150mm wide solid masonry walls. Favoured by builders and site managers for its robust support under demanding conditions, this 900mm lintel is ideal for openings requiring strength to carry heavy loads such as concrete floors and point loads. Please note, lintels are supplied as individual units and must be installed with correct bearing and support.

Application

Used primarily in solid wall construction, the HDBOX/K-150 lintel supports structural openings like doorways and window frames. Its heavy duty rating means it can safely bear the weight of wet masonry above as well as additional loads from concrete floors, making it a reliable choice for load-bearing walls on serious projects.

Box lintel for solid masonry walls

The perforated box lintel design offers a plaster key along its length, promoting secure finishing. It is essential to provide a minimum end bearing of 150mm on each side of the opening, with the lintel bedded on mortar. To ensure structural integrity and speed construction, propping the lintel during installation is strongly recommended. For further technical advice or assistance, please contact our sales team.
