/diy/ - Do It Yourself

>>2703451
I’m trying to install this pullup bar in picrel interior door frame: https://www.amazon.com/dp/B09RQVG3LH

It mounts with 4 lag bolts that are supposed to go into a king stud. The yellow stickers where I found metal with a magnetic studfinder. I didn’t find any metal 3” from the door edge, but I guess the drywall could be mounted onto the jack and not the king.

If I install the lag bolts where the pink stickers are, will I be safely in a stud that can support 200lb?
Or should I drill to look for a king 3” from the door edge?
How can I make sure that I’m centered in the stud?

If it matters, the ceiling is about 4’ above the door frame, and behind the right side of the door is a perpendicular interior wall.
