I've been wondering whether or not to buy a bar like this one: http://www.amazon.com/gp/product/B001ND04U4?ie=UTF8&tag=toubyanipo-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=B001ND04U4
The thing is, I live in a dorm where there are "fake walls", so they're not as strong as it should be. Another thing is, the wood above the doorway (I'm sorry, English is not my native language) is about 2cm thick (<1 inch).
Will this bar be able to hold me without breaking the wall or door? I only weigh 85kg (180lb ish)? And are there other/better bars that cost as much, or less?
Oh and on another note, the grippers for "neutral grip" are sometimes showed on the videos of the ad, but I don't see them on the box? How are they attached, do you have to buy them separately or something?
Any help is appreciated!
