If anyone is interested in these,
here are the dimensions for the enclosures.
All sizes given in mm & are approximate.
125 long
72 wide
50 deep (at rear)
20 deep at front
I'm not too sure of what amount of degrees the taper/slope is at & I don't have anything to measure it with. I'd guess it at around 30deg or so, but my maths is atrocious so..........
They don't look the prettiest in the photos, but they scrub up well with a little 1200 grit or some wire wool, & I'll burnish any rough edges with my windy!
Supplied with six 3/8' x 4 self tapping screws.
It's better to have it & not need it, than to need it & not have it!
