Details

The Keystone B/K-50 single leaf cavity wall lintel at 2550mm length is a dependable structural component tailored for builders, contractors and site managers working on cavity wall constructions. Designed to work alongside inner leaf concrete lintels, this product provides reliable support where it counts. Please note, the lintel must be installed with a tight-fitting timber batten to avoid twisting.

Application

Specifically crafted for cavity wall builds, the B/K-50 lintel supports openings such as doors and windows by bearing loads from above. It’s ideal for standard duty projects in residential and commercial developments where a single leaf lintel is required. The lintel’s compatibility with different cavity widths allows flexibility on site, but it is important to select the correct size to match your cavity dimension—in this case 50mm.
