KEF HTC2001.3 centre wall mount

[ajfoggy]

Hi all,

Just putting my new kit in and have a KEF htc2001.3 centre to wall mount. The problem is that I can't get it tight enough with the bracket.

I'll try and explain, if I have the centre horizontally the speak keeps dropping to the left or the right because the weight is of centre. I have tightened up all the screws I can find but it still loose.

Any ideas please
