Adrian,

Thanks for the detailed reply.

I have fitted these and they are incredibly badly designed.

They sound it. I'm grateful for advice based on your actually having
worked
with them. Did you use the ones from TLC, or a similar product from
another
source? I know I've seen a very slightly different design somewhere - I
thought it was from Screwfix but I can't find them on their website, so I
suppose it must have been another supplier.



They were from TLC (Merton)
