Dunns head extension bridge for snooker rest

I've used one of these since the 1990s and I had just lost my other one and didn't realise how often I do use it. Can't be without it now.

Great idea, but too loose on the rest. As a result, it slips upside-down as the cue slides along it. It needs to be a tighter fit.

Practical, an serves its function

I used this once and the rest head I put it on was too narrow and it swivelled on the rest head nearly causing me to make a foul shot so it depend on the thickness of the rest head.

Brought 4 sets of these for the snooker team I am in but was told that they do not fit the snooker rest as the diameter is too big and just spins around so my team mates were not impressed with me getting these

The join line down the middle is weak and susceptible to snapping all the way down. This inevitably pushes the bridge out of place so it is not in the correct position as shown in the pictures.

Way too loose

Does what it says,fits easily on to a snooker rest nice extra for my case.
