Glad you got your first batch in Dave, more on the way
Ecotech stated to us that not everyone will want to use a kit so adding it would unfairly increase the price for those that dont, and I think Ecotech are right in this policy. The units do come with 4 x M5 eye bolts
Each corner bolt has a threaded screw in it this is M5 thread so you can make your own.
To be fair to Ecotech, other LED companies also do not sell hanging kits included and Ai are no different.
