Details

The Keystone X/K-70 Extreme Duty Cavity Wall Lintel is a robust structural support designed specifically for heavy load applications in cavity wall construction. Suited to builders, contractors, and site managers handling serious projects, this 600mm lintel reliably supports openings where cavity widths range between 70mm and 85mm. Please note, correct installation including lateral restraint is essential to achieve the stated loading capacity.
