The SL150 is used above masonry openings in 150mm cavity walls where a standard-duty lintel is appropriate. Check the cavity dimensions, wall leaves, opening span, bearing and imposed loads before specifying. For more demanding loading requirements, review the relevant medium-duty or extra-heavy-duty alternatives.
