Bought some 2/0 trailer hooks for spinnerbaits and the plastic tubing that comes with it is the kind that hold the trailer hook in place. I want the type that will allow that hook to be free swinging. Can I buy a sort of keeper like that? Who sells trailer hooks that work like this right out of the pack?

Put the hook on and then the tube or keeper. I hole punch "keepers" from Planter's Peanuts or Cafe Bustelo lids. Cause they go well with beer, and I like strong coffee respectively 

 I punch out  keeper disc  from a piece of inner tube .

You know you can patch those.   I cut a length of 700c tube ( the ultra light presta valve butyl ones) and make "custom" grip covers. I also slide a short section over the threads on the reel seat. Of course I've been using tennis over grip on my fishing handles for over 20 years. Stainless spokes are the best large spinnerbait/buzzbait wire, and tandem brake cables work well for shark rigs. Guess what I do for a living....  

 

you can use the tubing that came with it. just cut them in half, slide trailer hook on, then the piece of tubing over the barb.

Cut the little nob off the back of these suckers.  Best trailer hook keeper I've used.  If you don't wanna order online, you can find them at Michaels craft stores.

They make a tool for that.

I figured this out 30 years ago or more. Just get yourself a paper punch and a plastic coffee lid. Punch out a bunch of small circles and force the main hook through the center of one - after you put the trailer on obviously!

Like this.
