I’ve got a dormer in my room (pic related) that I want to put a pull-up bar in because I want to be able to deadhang without my feet touching the floor, and none of the doorways in my house are tall enough. It measures just over 37” across, and the longest extendable pull-up bar I could find online is 36”. I was thinking of adding wooden blocks to each end of a pull-up bar, but I'm not sure how I'd support the blocks. I'm trying to avoid drilling anything into the wall.



Any suggestions?

Another view

how are you planning on hanging a pull up bar between two pieces of drywall that will support 100% of your weight without drilling into the wall?

Well, the idea was to use something like this

If you're thinking you can just treat it like a doorframe pullup bar, frame out for doors have significantly more rigidity to them. And bars still wiggle/outright fall out of them all the time.

It would have to be screwed into the studs to support your 425 lb weight. That bar that pushes against the wall will either fall down or will push so hard it breaks the drywall. You could just screw a 2x4 into the studs and when you're done with it fill the holes with a little putty or paint over them

The dormer walls are brick and plaster, not drywall. Do you think that would be rigid enough?

You'd be better knocking something together with 2×4's and a pipe. Get creative enough and you could fold it away under the bed when not in use

How do you think the extendo will work if the walls are sloped out the bar will just fall down you won’t be able to get a tight grip

Don't bother, because that's the way you do it if you want to do it right. Worst case scenario is you have to fill like 6 screw holes with spackle when you take it down which will take you all of a few minutes and a $5 tub of spackle.



Don't do this. The amount of outward force required on those small contact patches to keep that firmly in place with a person yanking up and down on it is immense. Best case scenario it cracks the drywall/plaster, worst case scenario it pushes the dormer walls out.

Masonry is quite bad at dealing with lateral forces.

imagine being this naive that your gonna believe some ching chong and his engrish me love you long time promises, lmao

This says the static friction coefficient between wood and cardboard is roughly 0.3 -- if that's the case and the bar has a 440 lb capacity.. assuming you're perfectly centered and the vertical reaction at one end is 220 lbs, then the horiztonal component required to develop 220 lbs of vertical friction resistance against the wall would be 734 lbs outward force.

>is immense.

It's not even a kip ;)
