The Jonard RJ45-625 is a bag of 25 CAT6 RJ45 pass-through connectors, a good size for the truck or a quick repair. They fit CAT6 and CAT6a cable, and the three-prong contacts work with solid or stranded conductors. The wires feed out the front of the plug, so there's no measuring or pre-cutting: set the order, crimp, and trim. The clear polycarbonate housing shows the wire order before you commit, and the contacts carry 50 micro-inches of gold plating. They're UL 94V-2 rated, RoHS compliant and made for the UC-4569 crimper. For bigger jobs, there are packs of 50 (RJ45-650) and 100 (RJ45-6100).
