Details

The Keystone HD/K-150 WIL is a specialist heavy duty lintel engineered to support cavity walls with a 150-165mm cavity width, specifically accommodating wide inner leaf blockwork of 125-150mm. Designed for builders, contractors, and site managers, this lintel delivers reliable structural support for door and window openings in robust masonry work. Please note that this lintel requires correct installation practices, including propping during construction.

Application

This lintel is ideal for cavity wall construction where a strong, wide inner leaf support is needed. It provides dependable load-bearing capability for openings such as doorways and larger window apertures in blockwork walls. Installation best practice includes ensuring the inner leaf blockwork is firmly built against the lintel face, with no more than 25mm overhang beyond the flange. Propping the lintel during build accelerates construction while maintaining safety and alignment. A mortar bed placed on top of the blockwork before laying floor units ensures even load distribution across the lintel.
