    Hello,
    I've been using a couple of Strongboys to support lintels and things no problem.
    Now I want to put them in a cavity brick wall to make a small opening. Do I need only a horizontal cut between the brick courses to let the strongboy in about 9" or do I also need to make a vertical cut for the slanting bit of the strong boy, so that it slides right in almost to the acrow?.

    for an opening that size we would only prop the one or two joists (if any) that would be sitting on the blockwork immediately above the opening.
    one acro and a thick batten would suffice.
