they are the standard ones with a plastic thing that screws into the
top corners from the inside, and has 2 screws for adjustment. the
sticking out bit is right next to the side panels of the cabinet. my
question is, do you have to position the wall brackets exactly, so
that they will not get in the way when you adjust the cabinet position
back against the wall. ie level it up, bring the top into the wall
instead of sticking out. this seems strange to me as it would be
hanging the cabinets on the outside edge of the brackets.

if anyone know what im talking about please reply!
