Details

The Keystone XHDT/K-70 is a robust extra heavy duty timber frame lintel, precisely engineered for use in 70-85mm cavity walls. Specifically designed for builders, carpenters, and contractors working on timber frame structures, it delivers reliable support for large openings where strength and stability are critical. Please note, this lintel must be installed with restraining clips and a timber pinch batten to ensure safe positioning during the build phase.

Application
