Maximum width side to side = 528mm
Maximum width front to back = 135mm
Depth of side turndown = 6mm
Length along angled side = 132mm
The leading edge has a slight curve that protrudes beyond a straight line drawn between the leading edge corners by 12mm.
The trailing edge is straight but curves round to meet the angled sides with a turn of approximately 18-20mm radius at either end.
Hope this helps.
Cheers, Brian
