Details

The Keystone CFS/K-50 WIL 4800mm lintel is engineered for extra heavy duty support in cavity wall applications where the inner leaf is wider. Trusted by contractors and site managers, it’s designed to carry substantial loads over openings with cavity widths from 50 to 65mm. Please note, lintels must be propped during installation to ensure safety and build speed.

Application

Specifically made for 125-150mm wide inner leaf blockwork, this lintel provides robust support over doors, windows, and other structural openings in cavity walls. Its design ensures the inner leaf blockwork does not overhang the lintel flange by more than 25mm, maintaining structural integrity. For optimal load distribution, a mortar bed should be laid atop the blockwork before floor units are positioned.
