This cavity wall lintel from Keystone Lintels Ltd is manufactured in galvanised steel and designed for use with cavity widths of 70–85 mm. At 1500 mm in length, it supports the formation of openings in masonry cavity walls where high load-bearing capacity is required.
Suitable for general building projects, the lintel is typically installed above windows, doors or other structural openings in external cavity walls with an inner leaf of 140–150 mm and an outer leaf of 102 mm. The extended end bearing of 200 mm ensures stable seating into the supporting masonry.
