Details

The Keystone HD/K-150 Heavy Duty Cavity Wall Lintel at 3300mm length is designed for builders, site managers, and contractors requiring a reliable structural support for cavity walls with widths from 150 to 165mm. Its robust construction ensures dependable load-bearing performance for serious building projects.
