Details

The Keystone CFS/K-50 WOL is an extra heavy duty cavity wall lintel engineered specifically for wide outer leaf walls with cavity widths between 50mm and 65mm. At 4650mm in length, it provides robust structural support for large openings where strength and reliability are critical. This lintel is a trusted choice for builders and site managers working on demanding projects that require dependable load-bearing solutions. Please note that correct installation practices, including prop work, are essential for optimal performance.

Application

This lintel is designed for use in cavity wall construction featuring an outer leaf blockwork width of 125-150mm. It supports window and door openings in heavy load-bearing walls, helping distribute structural loads evenly. Builders should ensure the outer leaf blockwork does not overhang the lintel flange by more than 25mm to maintain wall integrity. It is advisable to prop the lintel during construction to facilitate a quicker build process and enhance safety. Applying a mortar bed on top of the blockwork before placing floor units ensures even load transfer.
