Ok, now that I have your attention.
What alterations need to be done to a typicle commercial, 16" on center, metal stud wall with 5/8" sheet rock to support a 200 Ib load that can be pulled 36" away from that wall.
I am estimating that the wall will have to be able to hold 800 Ibs to safetly have that load anchored to it.
Typicly in this situation I use a ceiling mount and be done with it but the job demands it be done this way. I am assuming that the wall need to be opened, double wood floor to ceiling studs will have to be installed and anchored across about studs. Then the new studs will need to be blocked together with 3/4" plywood. then that wall can be sealed back up and the load can be anchored to the blocking.
Thoughts?
