I live in an apartment, and this pull-up bar hangs perfectly on my bedroom door. The only catch is, I can't shut the door while the bar is on there, but that's OK...it's very easy to remove and put back in place when I want it. Also, it's very easy to set up, out of the box. You just unfold the 'arms' until they click into place and then hang the bar where you want it! No tools needed...it's all one piece. This is obviously a sturdy item which stays in place perfectly well while in use, plus it has those little cushions on the edges of the bar which rest against the door frame, so, no damage to the frame. :)Highly recommended! Just be sure to measure your door frame before purchasing. According to the description, this bar will fit door frames which measure between 22-36". The door frame I'm using is 34", and the bar fits great.
