Details

The Keystone HDBOX/K-100 is a robust, heavy duty box lintel engineered to support openings in 100mm solid walls. Ideal for contractors and site managers handling serious structural projects, this lintel reliably carries heavy loads such as concrete floors and point loads, helping maintain the integrity of your build. Please note all lintels must be propped during installation and bear a minimum of 150mm at each end on mortar.

Application

Specifically designed for use in solid masonry walls, the HDBOX/K-100 lintel supports openings where heavy loading conditions occur. It is commonly used to span window and door openings in solid 100mm walls, particularly where concrete floors or concentrated loads transfer weight above the opening. The perforated surface ensures strong adhesion for plaster or render finishes, integrating seamlessly with surrounding masonry.
