Details

The Keystone HD/K-70 WIL heavy duty cavity wall lintel is engineered for professional builders and contractors requiring dependable support over cavity openings. Measuring 1800mm in length, it is tailored for cavities between 70-85mm and designed to carry 125-150mm wide inner leaf blockwork. This lintel is a practical choice when strength and reliability are essential on site. Please note, the inner leaf block must not overhang the lintel flange by more than 25mm to ensure proper load transfer.

Application

This lintel is ideal for supporting heavy structural loads above window and door openings in cavity walls with wide inner leaf construction. It provides dependable performance in both new builds and renovation projects where cavity widths fall within the specified range. Propping the lintel during installation is advised to speed construction and maintain stability. Mortar bedding on top of the blockwork before laying floor units ensures even load distribution through the lintel.
