Sorry mate ,I cant find a pic but I`ll try and describe it.
The snood swivel is crimped on low down to the lead.
An inverted clip is placed at the top of the rig.
When the snood is tied on it goes up and over the the inverted clip and the hook is clipped down at the bottom of the rig.
It`s hard to explain this way.
If anyone has a link to a diagram for this rig it would be appreciated.
