Hello Radek,
Here is a picture of one of my pintle hooks. Looks like just a slight radius. I used 5/8" bright steel shafting to make the latch handle.
Regards Terry.
Hi Terry,
many thanks for the picture and info what to use on the latch handle.
To all:
It is possible that the radius is made from trailer towing eye? It looks like so.
Radek
