Details

The Keystone CFS/K-50 WIL lintel is an extra heavy duty cavity wall lintel designed specifically for wide inner leaf applications. Ideal for builders, contractors and site managers, it supports openings where cavity widths range from 50 to 65mm and inner leaf blockwork is 125-150mm thick. Please note that the inner leaf block should not overhang the lintel flange by more than 25mm to maintain structural integrity.

Application

This lintel is engineered to carry substantial loads over cavity wall openings such as windows and doors in residential and commercial builds. It is particularly suited to wide inner leaf cavity walls where robust support is essential. For optimal performance and safety on site, it is recommended that lintels are propped during installation to facilitate faster construction and to evenly distribute loads.
