These are the top and bottom sides for the wall units from Lansdowne Boards. No mistakes or inconsistencies here (for once), this is how they do it.
Of course, if they put the slot for the backing board on the other side, the holes for the cam system would end up on the outside of the unit. Which won’t be visible. In this design, the cams end up inside the unit, which is visible.
Doesn’t look too bad though.
I still havn’t figured out how to avoid holes in the backing board. Using their hanging system, one ends up with two holes in each upper corner, and two holes across the bottom. Using what I did here, I ended up with four holes. I guess bodyputty and paint is a solution…
Looks real good – well done!
