Swimming pool coping - Can you buy right angled coping ?

[meljave]

Am putting in a liner pool and want to hide the joint between coping and liner. I have seen a video on Youtube with someone laying right angled pavers/coping ie they sit on top and also go down into the water. Does anyone know where I could get something like this ? I realise that they would make changing the liner difficult but am prepared to face that when the time comes! Could be concrete fake stone or resin or even brick but they need to go down the side of the pool about 20cms. All help gratefully received - thanks.

something like this?

Yes indeed something like that ! not sure about the extra bit at the bottom though can't see that it would matter either. Do you make them ?
