Details

The Keystone HDBOX/K-150 is a heavy duty solid wall box lintel designed specifically for 150mm thick masonry walls. Ideal for builders and site managers working on demanding projects, it reliably supports heavy loads such as concrete floors and concentrated point loads. Please note that lintels require a minimum 150mm bearing at each end and should be bedded on mortar for secure installation.

Application

This box lintel is commonly used to span openings in solid masonry walls where heavy duty load support is essential. Its robust design makes it suitable for use in structural openings supporting wet masonry, concrete floors, and significant point loads. The perforations along the lintel’s length provide a secure plaster key, ensuring a neat and durable finish once installed. Propping is recommended to maintain stability during construction and speed up the build process.
