Details

The Keystone XHDT/K-50 4350mm lintel is engineered specifically for timber frame cavity wall applications where extra heavy duty load support is essential. Tailored for builders and contractors working on robust timber frame projects, it ensures stability and reliability across openings with cavity widths between 50 and 65mm. Please note that the lintel must be fitted with restraining clips and a timber pinch batten to prevent rotation during construction.

Application

This lintel is primarily used in timber frame cavity walls to support structural loads over wide openings such as windows and doors. Its extra heavy duty rating makes it suitable for demanding building projects where high load-bearing capacity and long-term stability are critical. Installation requires propping during construction to speed up build time safely. The lintel’s design accommodates cavity widths from 50mm up to 65mm, with wider cavity options available in the Keystone XHDT/K range.
