Details

The Keystone S/K-90 is a standard duty cavity wall lintel, measuring 900mm in length, designed specifically for builders and tradespeople working on cavity walls with widths of 90-105mm. This lintel provides reliable structural support for window and door openings, making it a practical choice for everyday building projects. Please note, lintels must be propped during installation to maintain safety and construction speed.

Application

Ideal for use in cavity wall construction, the Keystone S/K-90 lintel supports openings such as windows and doors by spanning the cavity and bearing the load from above. It works best when blockwork is built tightly against the inner face of the lintel, with a mortar bed applied on top before floor units are laid to ensure even load distribution. This lintel is suited to standard duty requirements, commonly found on residential and light commercial sites.
