Just put your trailer hook on the main hook and then just put a piece of rubber over the hook. Just cut it about the size a little bigger than the hole on the trailer hook eye. This will let the trailer wobble behind the spinnerbait. If you are throwing it in open water turn the hook down. If you are throwing it in grass or cover than turn the hook up and it will be less snaggy. You can also use a small tube to stick over the eye and then run the main hook through it if you want to make it solid. EB
Cabela's have the little rings that go over the main hook to hold the trailers on too.
