It failed on the default vertical layout on the bed on two prints the came lose at the exact same spot. I ended up refacing it to lay flat and had no problem. Nothing major and it works perfectly to hang my blower.
as I was attaching to a brick wall it didn't seem to stick out enough to avoid rubbing leaf blower against the wall when putting in/out. So packed it out with thin strip of wood and works fine. Could just be issue with lumpy old brick walls.
