Details

The Keystone HDBOX/K-150 heavy duty solid wall box lintel is purpose-built for construction professionals working with 150mm solid masonry walls. At 2550mm in length, it provides robust support for heavy loads such as concrete floors and point loads, making it a dependable choice for structural openings. Please note that proper bearing and bedding are essential for optimal performance.

Application

Designed specifically for 150mm solid wall openings, this box lintel is commonly used to span openings requiring heavy duty support, including lintels over doorways and windows where concrete floors or concentrated loads are present.

It is essential to provide a minimum bearing of 150mm on each side, bedded firmly on mortar, and to prop the lintel during construction to maintain structural integrity and facilitate a smooth build process.
