So I live in a nice sized studio apartment in a small complex building. I have always wanted a heavy bag in my place. So I bought a 70lbs bag, got a steel pipe cut for the 41" wide entrance from the hallway to the room, the mounts for the pipe with decent sized wood screws and some small ratchet straps to hold the bag. The door way is all drywall, so it was easy to screw the mounts into it (4 screws each) on either side.
Everything seemed fine, it held the wight, the straps worked perfectly. BUT. Second punch in, the left mount tore right off and everything came tumbling down.

My question is - What can I use to secure the pipe into the drywall that will take the 70lb wight, and the force of my punches, without tearing out of the wall (fast or over time)

 

The actual framing in that wall is at the corner.
You need to move your mounts to the end of the walls.

 

I've had a couple 90# bags and mounted both from the steel beams in the basement. There is a lot of weight, a lot of force, going into that wall.

I'll bet with time it will rip the studs out of the wall!

 

Good thing I'm not the landlord and saw that in one of my rentals.
