Johnson fittings?
If you obtained Johnson fittings, they probably have a description of the type of tool you will require on the back of the package.For hand swages, there are two types, one for the copper sleeves used on rigging, the other for crimping the stainless tubes on life line hardware. While they appear similar, they do have slightly different and significant crimping patterns.For my Catalina 22, I have both tools, but only because the wire sizes for this vessel means the cost of these tools, in terms of their expected use, is, for me, within reason.Depending upon your wire size, the life line hand swag tool should be available at either Boat US or west Marine. I got mine from West Marine.
