VEVOR Snow Roof Rake Mount Adapter
Mine broke after 30 seconds of use. Ok, is written in the manual, that you should really screw it well. But anyway, here is Version 5 of a replacement mount.
Important: You need a M8 Thread Cutter to recut the printed Thread. You need a long M8 Screw or a M8 thread rod for stability. The holes are not 100% fitting on the vevor rod. I cutted it off and made new holes.
