Details

The Keystone BOX/K-150 Solid Wall Box Lintel at 1350mm is engineered specifically for builders and site managers working with 150mm wide solid masonry walls. This reliable, standard duty lintel provides essential support over internal openings, ensuring strong load-bearing capacity while accommodating plaster finishes thanks to its perforated design. Please note lintels must be propped during installation and bear a minimum of 150mm on each side, bedded on mortar for optimum performance.

Application

This box lintel is ideal for creating strong, stable lintels over doorways and internal openings in solid brick or block walls typically 100-215mm thick. Its perforations act as a plaster key, making it well suited for plastered internal walls. It supports the full weight of wet masonry immediately after installation, helping to maintain build speed and structural integrity on site. Proper end bearing and temporary propping are essential to meet best practice standards.
