Two cleats on at the wrong level... about 300 low?
Bingo! Two cleats 200mm out.
Two bits of 150 x 100 stainless box in there to bring them right. A bit of a bodge but all hidden away and better than chopping the cleats off and damaging the galv.
Would have fabbed/galved some bolt-on cleats but no time.
Damn was typin on the page one under the picture
