One for my punching bag and one for my rip60 Slingtrainer. Because I was afraid that it could not hold in the ceiling I have this heavy-duty dowels concerned holding per dowel to 350kg. At the 3rd hole I met steel. Because I did not want filling again, I tried it with 2 screws. And it holds bombproof. I also have the same inserted a short training session. The bracket holds sovereign. For me, a strong buy recommendation.
