Details

The Keystone HDBOX/K-100 900mm INS is a heavy duty solid wall box lintel designed specifically for builders and contractors working with 100mm thick masonry walls. Its robust construction supports significant loads such as concrete floors and point loads, while the built-in insulation enhances thermal efficiency on site. Please note, this lintel requires a minimum end bearing of 150mm at each side and must be bedded on mortar for secure installation.

Application

This box lintel is ideal for supporting openings in solid masonry walls where heavy duty loading is expected, including structural floors and concentrated load points. The integrated insulation helps meet building regulations for thermal performance, making it a practical choice for energy-conscious builds. The perforated surface ensures a strong plaster key for seamless finishing, enhancing both function and aesthetics on site. Propping is advised during installation to speed up the construction process and ensure structural safety.
