Details

The Keystone HD/K-150 Heavy Duty Cavity Wall Lintel at 3900mm length is designed for builders and contractors tackling substantial masonry openings. Its robust construction supports cavity walls with widths from 150mm to 165mm, making it a dependable choice for projects requiring heavy load-bearing capacity. Please note that proper installation and propping are essential to ensure performance and speed on site.

Application

This lintel is ideal for spanning window and door openings in cavity wall constructions where walls have a cavity width of 150-165mm. It is routinely used in commercial and residential developments requiring strong structural support above openings. The lintel supports blockwork, which should be built tight against the inner face to ensure correct load transfer. A mortar bed should be laid atop the blockwork before floor units are installed to evenly distribute weight.
