REGARDING WALL THICKNESS:
As for all our lintels, each designation (eg. 'SL7') is available in a range of widths to suit different thickness walls, but they all have the SAME load capacity. Simply suffix the lintel with your wall, eg: SL7-100. View the PDF files for details.

they can be used for thick single wall applications!
