Details

The Keystone BOX/K-150 Solid Wall Box Lintel measuring 1800mm is a specialist structural support designed for internal openings in 150mm wide solid masonry walls. Ideal for builders, site managers, and contractors working on standard load projects, this lintel provides dependable strength and stability from the moment wet masonry is placed. Please note, lintels must be installed with appropriate bearing and bedding to ensure performance.

Application

This lintel is primarily used to span internal openings such as doorways or window spaces within solid 150mm thick walls, supporting the masonry above during and after construction. Its perforated box design offers a mechanical key for plaster, improving finish adhesion. It is suitable for standard load conditions where reliable structural support is essential. Proper end bearing of at least 150mm on each side is required, and lintels should be propped as work progresses to maintain site safety and construction efficiency.
