Details

The Keystone HD/K-70 is a heavy duty cavity wall lintel designed specifically for trade professionals requiring reliable support for medium-width cavity openings. Ideal for builders and contractors working with cavity walls between 110mm and 125mm thick, this 600mm lintel offers dependable load-bearing capacity to maintain structural integrity on site.

Application

This lintel is primarily used to span openings such as windows and doors in cavity wall constructions with cavity widths of 70-85mm. It is suited to projects where heavy duty support is needed to carry structural loads safely above openings. The lintel is installed with blockwork tightly built against its inner face, creating a strong, stable junction. It is recommended to place a mortar bed on top of the blockwork prior to laying floor units to evenly distribute the load. For safe and efficient installation, propping the lintel during construction is advised.
