I have this concept in mind:
Horizontal orientation "hanging" from the mounting bolts in the bottom.
I've designed a mounting hub,t hat would take advantage of both bolting positions.
I am uncertain how the bolt thread inserts in the chassis of the MTM are moulded to the structure... I am unsure how strong they would be in this application, or if it would be too much stress and could cause a failure/crack overtime.
I have considered extending my mounting hub in a way the wraps around the bottom a bit to help support from the lower edge, but if it's not needed then I'd rather be efficient/have a clean look to my concept.
Please leave me with some feedback for my project, so that I can keep moving forward.
Thank you!
PS.
I realize it seems simpler to just mount them vertically, please take my word on it, that it's a very unusually application of the MTM, and they need to be mounted as displayed, more or less.
