Details

The Keystone BOX/K-150 is a robust box lintel engineered for supporting internal openings in 150mm wide solid walls. Perfect for builders and site managers tackling standard load masonry projects, this lintel ensures dependable structural support and integrates easily with wet masonry works. Please note, the lintel must be installed with care to meet bearing requirements and ensure full load performance.

Application

This lintel is typically used above doors and window openings in solid masonry walls ranging from 100mm to 215mm in thickness. Its perforated surface acts as a plaster key, allowing for straightforward finishing once the masonry is in place. Keystone BOX lintels support the full wet masonry load immediately after installation, making them ideal for efficient build schedules. To maintain structural integrity and speed up the build, propping during curing is highly recommended.
