Details

The Keystone HDBOX/K-200 2550mm INS is a heavy duty solid wall box lintel designed specifically for 200mm thick solid masonry walls. It is a robust solution tailored for builders and contractors tackling demanding structural openings where reliable load bearing is critical. This insulated (INS) variant improves thermal performance, making it a smart choice for projects where energy efficiency matters. Please note, box lintels must be installed with proper bearing and bedding to ensure stability.

Application

Ideal for supporting large openings in solid masonry walls, this lintel is commonly used in the construction of residential and commercial buildings. It effectively carries heavy loads from concrete floors, masonry above, and point loads such as steel beams or heavy wall finishes. The integrated insulation helps reduce thermal bridging, supporting compliance with building regulations. Recommended for use where both structural strength and improved thermal performance are required. Always ensure minimum 150mm bearing on each end and mortar bedding for safe installation.
