Hi LC,
I am wondering if what you are seeking is actually the Clouser arm to which either a standard or saltwater set of jaws attaches. I own two travelers and have found that the standard jaws will hold most of the larger hook sizes very well. The Clouser arm being straight as opposed to the standard bent arm makes the tying of the long streamers a whole lot easier and is just a matter of switching over the jaws. Have a look at the Renzetti website and you may find what you are looking for. If your existing jaws are not functioning properly, they also have just replacement jaws available and repair services also available. HOPE THIS HELPS.
