Manfrotto 098SHB Variable Short Wall Boom with Variable Extends from 30.75-Inches to 48-Inches (Black)

i've got this manfrotto boom arm and i want to put it on the wall and i want to put it way up here just above the tv now i know i've got a stud here and i've got a stud here uh just because i put the tv up already and so i know that's where the studs are if i try to put it here on this stud it's going to be a little too far away this one's going to be a little too close so i want to try to get it somewhere in the middle so i've got a couple two by fours i'm going to try to tie those into the two studs so i'll be able to put it wherever the heck i want it i know i have a big truck i just have a little car so i bought these you can actually get these pre-cut to uh 24 inches so the next thing i need to do is i need to confirm where those studs are i'm going to be using this this is just a couple of magnets with plastic material on the back to prevent scratching up the wall so these are goi
