Allen Brothers, part number A473, Ronstan make them also. Force 4 sell them and also people like P@B, Sailboats.
These chocks are a tuning aid, helps to hold the mast in a desired position and also fill a gap to keep the sheets out!
When fitting chocks, may be a good idea to have a look at the tuning guides to see what is wanted from them rather than just fill a gap which some tape across the gap would do.
They have been covered in this forum if that’s any help, Chocks away Mate!!!!!
Many thanks Geoff and Colin. I have now ordered a set online and I have read the thread about mast chocks which is what I should have done first.
