I'd like to use this small sink in a powder room, but can't figure out how it mounts to the wall. There are large holes for lugs at the bottom, but if that's it the sink will tip and crack.
Does something go into the two upper holes? I've looked for brackets and nothing matches; they all use a French cleat system. I haven't found a guide to installing an old wall mount sink either; everything I found says "now install the bracket supplied by the manufacturer". Doh!
Edit: I understand that something is going to have to go into the top holes to secure the sink. I just don't understand what or how. The two top holes go into the sink and I have no access to the front. So I can't insert a screw or bolt there to stick out the back.
Edit 2: Added a couple more pictures of the back of the sink. I think making a cleat-type bracket like @eric-poole suggested just might work!
