Hey everyone! I recently bought a pull-up bar that I need to mount to the joists in my basement. My dad is worried that this could damage the joists because, as he puts it, a garage rafter is not the same as basement joists. I understand that the joists are crucial for supporting the weight of the house. I'm mainly curious about the safest way to mount this pull-up bar without compromising the joists.
1. Should I mount it directly to the joists or consider using a sister joist instead?
2. What size screws should I use, and is there such a thing as using too long of a screw?
3. After mounting, do I need to keep those screws in forever to maintain the joist's integrity? If I decide to move the bar later, can I just plug the hole with a wood peg?
Thanks for any insights!

Ignoring all the worried comments, mounting your pull-up bar directly to the joists is totally fine—if you live in a house built to standard code. Your floor joists can handle much more weight than just your body hanging from them.
1. Just go ahead and mount it to the joists.
2. Use the screws as specified by the manufacturer; they know what works best. The joists should be plenty strong enough compared to what the bar is designed for.
3. Drilling a couple of screws into the joist shouldn't weaken it significantly at all.
Don’t stress about it—your floor joists are designed for this kind of use!
While I get the concern, normal joists are built to support some serious loads and should handle a pull-up bar without any major issues. Here's my take:
1. I would suggest mounting it directly to the joists—just ensure they're not engineered lumber, which might be less reliable.
2. Use screws that the manufacturer recommends. Too long can risk compromising the joist's integrity, but as long as you're following guidelines, you should be good.
3. Once you put it up, you don’t need to keep the screws forever. If you decide to move the bar, filling those holes with pegs should be fine.
Just a little precaution goes a long way—stay safe!
I value your opinion—thanks for sharing! It's better to be safe than sorry, right?

Thanks for this! Just wanted to make sure I’m not causing more harm than good. It’s great to hear from someone who's been there before.
