I have a gate with a pull type latch. The latch is activated by pulling a stainless steel cable. I need to attach this cable to the latch. I want to loop the cable through the latch where a hole is provided for this attachment. I need to crimp a ferrule onto the cable to accomplish this. I need to use a swagging tool. Since I don't have this tool, can anyone advise what type of contractor or business I can go to, give someone 20 bucks, and have them crimp the ferrule?
