Details

The Keystone BOX/K-100 Solid Wall Box Lintel 2400mm INS is engineered for builders and site managers working with 100mm wide solid masonry walls. This insulated box lintel not only supports standard loads reliably but also enhances thermal performance, making it a practical choice for projects demanding both strength and energy efficiency. Please note, lintels must be installed with a minimum 150mm bearing on each side and are best propped during construction for optimal results.

The box design ensures it can carry the full wet masonry load immediately after installation, helping maintain build progress without delay.
