The Keystone S/K-50 Standard Duty Cavity Wall Lintel is engineered to provide dependable structural support for cavity walls with widths from 50 to 65mm. At 4200mm long, this lintel is well suited for builders, contractors, and site managers working on standard openings where reliability and ease of installation are essential. Please note, lintels should be propped during installation to maintain safety and construction speed.

Application

This lintel is typically used to span openings such as doors and windows in cavity wall construction, supporting the masonry above.
