Details

The Keystone HD/K-70 is a heavy duty cavity wall lintel, measuring 3900mm in length, designed specifically for builders and site managers working on substantial cavity wall projects. It offers dependable support for openings where cavity widths range from 70mm to 85mm. Please note the lintel should be propped during installation to maintain stability and aid construction speed.

Application

This lintel is engineered to support heavy loads above structural openings such as doors and windows in cavity walls constructed with blockwork. The blockwork should be built tight against the inner face of the lintel, with a mortar bed applied on top of the blocks before laying floor units to ensure even load distribution. Its robust design makes it well-suited for contractors and developers requiring durable and precise structural support on serious building projects.
