Hi recently purchased one of these.
www.anglingdirect.co.uk
Does anyone know which inserts I need to fit it to a 19mm square leg or a 25mm chair leg.
Most of the Korum stuff is now out of stock but have been told that Prestons stuff should fit.
Also have one of these and have same question.https://www.anglingdirect.co.uk/korum-anychair-adapter
Assumed this would be same size as the feeder arm but in fact it is much bigger.
Have seen these.

Thanks in anticipation.
