This extra heavy duty cavity lintel from Keystone Lintels Ltd is constructed from galvanised steel and designed for use in cavity wall construction. Measuring 3600mm in length, it is suitable for installations where a robust structural lintel is required to support significant loads above door and window openings.
Typically used on commercial or residential building projects, this lintel accommodates an internal leaf of 125-150mm and an external leaf of 102mm. Its extra heavy duty classification makes it a practical choice for projects that demand added strength at wider spans or where heavy wall loads need effective support during brickwork or blockwork construction.
