Details

The Keystone HDBOX/K-150 is a heavy duty box lintel designed specifically for use in 150mm solid masonry walls. It offers robust support for openings subject to substantial loads such as concrete floors and concentrated point loads, making it a dependable choice for contractors and site managers handling demanding structural projects. Please note, lintels must be installed with a minimum end bearing of 150mm on each side and should be propped during construction to maintain safety and speed up build times.

Application

This lintel is ideal for supporting door and window openings in solid brick or block walls where heavy loads are expected. Its heavy duty classification ensures it can carry the weight of wet masonry and concrete floors immediately after installation, helping tradespeople maintain efficient workflow on site. The perforations along the length of the box lintel create a strong key for plaster, improving the finish quality around openings.
