Details

The Keystone HDBOX/K-150 INS is a robust insulated box lintel designed specifically for 150mm thick solid walls. Ideal for builders and site managers working on demanding projects, this lintel supports heavy structural loads such as concrete floors and point loads with confidence. Please note, lintels are sold individually and must be bedded on mortar with the correct end bearing.

Application

This heavy duty box lintel is suited for creating strong, reliable openings in solid masonry walls where substantial load-bearing is required. The integrated insulation enhances thermal performance, helping meet modern building standards. Typical uses include supporting concrete floor slabs, heavy masonry above doorways or windows, and other critical load points in structural walls.

Type

Box lintel for solid masonry walls

To ensure proper performance and safety, a minimum end bearing of 150mm on each side of the opening is essential, with the lintel bedded on mortar. The perforated surface acts as a plaster key for a seamless finish. For faster construction, propping lintels during installation is recommended.
