Rowlock course
When constructing a rowlock course, support brackets are available as a complement to the formwork used for wall openings.
The support brackets adjust the height of the bearing surface to match the adjacent stretcher courses when constructing a half-brick or one-brick rowlock course. When using rowlock course supports, the length of the wall-opening form must be reduced by at least 10 mm compared with the opening width, to ensure that the brackets fit between the form and the masonry.
