Details

The Keystone HDBOX/K-100 is a robust heavy duty box lintel, engineered specifically for 100mm solid wall applications where high load-bearing capacity is essential. This 1350mm lintel offers dependable structural support for concrete floors and concentrated point loads, making it a trusted choice for builders and site managers handling demanding projects. Please note, lintels must be properly bedded with a minimum 150mm end bearing on each side.

Application

Designed for use in solid masonry walls of 100mm thickness, this box lintel is ideal for spanning openings such as doorways and windows where heavy loads from floors or structural elements must be transferred safely. Its heavy duty rating ensures it can carry the full wet masonry load immediately upon installation. The perforations along the lintel length act as a plaster key, aiding a strong finish. For efficient and safe construction, supporting props are recommended during installation.
