Details

The Keystone HD/K-50 3300mm lintel is a specialist heavy duty cavity wall support designed for builders, contractors, and site managers tackling substantial openings. Its robust construction offers reliable load-bearing capacity for cavity widths of 50-65mm, making it a trusted choice for structural walls requiring durable lintel solutions. Please note, lintels should be propped during installation to ensure safety and build speed.

Application

This lintel is engineered to support openings in cavity walls, such as doorways and large window spans, where heavy loads from blockwork and floor units must be safely transferred. Builders should bed blockwork tightly against the lintel’s inner face and apply a mortar bed on top before laying floor units to ensure even load distribution. Its heavy duty rating suits demanding projects, including commercial builds and robust residential structures.
