Details

The Keystone XCFS/K-70 WOL 3450mm lintel is an extra heavy duty cavity wall lintel specifically engineered for wide outer leaf applications. It’s designed to support substantial loads over openings where cavity widths range between 70 and 85mm, making it a reliable choice for builders and contractors handling serious structural work. Please note that proper installation practices are essential, including correct blockwork positioning and propping during construction.

Application

This lintel is ideal for use in cavity walls with outer leaf blockwork between 125 and 150mm thick. It supports openings such as large windows, doors, or other structural gaps where heavy loads need safe distribution. Tradespeople should ensure the outer leaf block does not overhang the lintel flange by more than 25mm to maintain structural integrity. Propping the lintel during build stages is recommended to speed up construction while ensuring safety.
