Details

The Keystone BOX/K-150 is a 3000mm solid wall box lintel engineered for builders and contractors working with 150mm wide solid walls. Offering dependable support for internal openings, this lintel is a smart choice for those needing reliable load-bearing performance on site. Please note, lintels require a minimum end bearing of 150mm on each side and must be propped during installation to maintain structural integrity.

Application

Designed for use in solid masonry walls between 100mm and 215mm thick, the BOX/K-150 lintel carries the full wet masonry load immediately upon installation.
