Manfrotto 059WM Single Background Hook - Wall Mountable - Set of 2

Definitely not. These need to be bolted to the wall or ceiling to carry the weight of a roll of seamless paper.

These hooks only work with an Expan Drive due to the narrower slot they offer.

You can use it on a wall or ceiling assuming its securely mounted.

Yes.

Well ; the paper roll you want to hang its no more than 40 pounds ( 20 kilos ) it isn't? ; in my personal experience the Hook will easily support it, if it is properly installed , it's not the resistance of the metal hook, its the way you installed the main issue, I hang a Vinyl background 8' x 20' on it with no problem.

You don't need the autopole. I have several hooks mounted to my wall. Make sure you hit a 2x4 in the wall. Drywall will not hold the weight in my experience. Good Luck!

I use the brackets with 5' x 15' vinyl background. The brackets are strong but be careful they are mounted with screws into 2 x 4's behind sheetrock. Sheetrock with no backing may result in failure of the bracket.

You don't need to be 100% accurate because the non chain side of the drive set gives you about 2 inches of play. Thuis can be seen clearly in its product images. When I mounted it I first set up the drive set on the paper, set the holding part on the non drive side to the middle, and than figured out my measurements. When I put it up I had not gotten it perfect, but the 2 inches of wiggle room made up for it.
