Know a lot of people use these to mount fingerboards etc. Have read good reviews.
Have also read a couple of reviews of them damaging fragile door frames. What are peoples' experiences on here?
Specifically I am worried about the downwards force exerted on the reverse side (i.e. the side opposite the bar you pull on) by the little nubbins. The reason I don't do doorframe pull ups is that I am pretty sure I would rip off the frame. I am only about 11st but the flat I'm renting is built to less than exacting standards.
Reckon the nubbins would have a good chance of puncturing my wall also, but figure I can protect that with a bit of wood to disperse the horizontal force more evenly.
So what's the powerbar feedback?
Cheers.
