Details

The Keystone X/K-50 WIL is a robust extreme duty lintel designed specifically for cavity walls with wider inner leaves. Ideal for builders and site managers working on substantial structural openings, this lintel provides reliable support for cavity widths from 50 to 65mm and inner leaf blockwork thickness between 125 and 150mm. Please note that the lintel must be laterally restrained during installation, and images are for guidance only.

Application

This lintel is suited to heavy load-bearing applications in cavity wall construction, particularly where wider inner leaves are specified. It’s commonly used by contractors and developers on projects requiring strong, dependable lintels to span large openings such as doors, windows, or service ducts.
