Details

The Keystone BOX/K-100 Solid Wall Box Lintel (INS) is a specialist structural component designed for builders and site managers working with solid masonry walls between 100mm and 215mm thick. Its built-in insulation boosts thermal performance, making it an ideal choice for internal openings where energy efficiency is a priority. Please note, the lintel is supplied loose and requires proper end bearing and support during installation.

Application

This box lintel is engineered to support the full load of wet masonry immediately after installation, providing robust and reliable structural support for internal openings such as doorways and window reveals within solid walls. It suits standard load-bearing requirements on site and is essential for maintaining structural integrity while allowing for efficient construction schedules. Proper bedding on mortar and a minimum 150mm end bearing on each side is critical for performance, along with temporary propping to speed up the build process.
