i'm lookin for a solution to hang this in my backyard. So i have 2 post where i can run some sort of string or rope across and then hang the projector on it.
I need help locating this string or rope where it can be mounted and be tight with tension. if you guys can think of something, please suggest.
I was thinking to put a bracket on each post and run a string but i think the string will get lose, so i need something that will be tight.
attached a drawing for reference
