Details

The Keystone B/K-70 single leaf cavity wall lintel is a specialist structural component tailored for builders and site managers working with concrete inner leaf walls. Its 900mm length and robust design make it a dependable choice for standard load-bearing applications where cavity walls require reliable lintel support.
