Details

The Keystone HDBOX/K-100 is a robust heavy duty box lintel specifically engineered to support openings in 100mm solid masonry walls. Its insulated design (INS) offers enhanced thermal performance, making it an excellent choice for contractors and site managers focused on both structural integrity and energy efficiency. Please note that this lintel must be installed with proper bearing and bedding to meet load requirements.

Application

Ideal for heavy duty load-bearing situations, this lintel supports concrete floors and point loads above openings such as doors and windows in solid walls. The integrated insulation helps reduce thermal bridging, meeting modern building standards without compromising strength. It’s suitable for new builds and refurbishment projects where reliability and compliance are essential. For best results, lintels should be propped during installation to speed up construction and ensure safe load transfer.
