cheers for the replies! i may have to mount it on a pull up bar
With timber frame walls there are almost always upright supports either side of the door jambs. Also there will be timber running across the ceiling between the pieces of plasterboard.You can see them in the first installation on this page.http://www.lets-do-diy.com/Projects-and-advice/Walls/Building-a-stud-partition-frame.aspxAffix timber to these joists (make sure you've definitely found them by using a stud finder if unsure) then fix the fingerboard to the timber.I hope that makes sense.
