I used to use that hook but now use this one:
WICHARD
Stainless-Steel Snap Hooks

Tornado Alive has a picture that is close to how I set mine up. I do not use a block to pull it into the crossbar. I splice the bungee into the chicken line at the point that I want to be furthest inside. If you have a large enough hole in the end of the crossbar you can tie it so that the hook will lay right inside the hole. I use a small line that will hang out to retrieve when needed. This is the way to keep it from hooking a line inadvertently.
