Details

The Keystone S/K-50 WIL 3750mm lintel is a robust, standard duty support designed specifically for cavity walls with wide inner leaf blockwork. It’s tailored for builders, site managers, and contractors needing reliable structural support over openings where cavity widths range from 50 to 65mm. Please note, this lintel is intended for use with inner leaf blockwork between 125-150mm thick, and block overhang on the lintel flange must not exceed 25mm.

Application

Ideal for supporting masonry above window and door openings in cavity walls, this lintel ensures stability in standard load conditions. Its wide inner leaf design accommodates thicker blockwork, common in residential and commercial builds. For optimal results and to maintain site safety, propping the lintel during installation is advised, which also helps speed up the construction process. If you require further technical guidance, Keystone’s Technical Office is available to assist.
