Hammond emclosures

Those using hammond encloures:

How are you fixing the enclosure to the tractor?

Which Hammond enclosure? Do you have part numbers?

I’m currently using some strong sticky backed velcro. Not ideal but it is pretty solid and was a quick fix as I move my enclosure between 2 tractors. I’m thinking long-term some rail\clamp system bolted to the bottom of the enclosure and cab floor. Interested to see other solutions
