Even down to the simplest components, CURT is always looking for ways to improve your towing experience. CURT wire terminals are vinyl-insulated and available in a range of sizes to fit different gauges of wiring and different size bolts. Ring terminals are preferred for their fixed design, screwing into place and requiring the fastener to be completely unscrewed for removal. These ring terminals are color-coded and designed to fit 12-10 gauge wire and a 5/16" stud. This package includes 100 terminals. CURT terminals can be used for all sorts of wiring and rewiring projects on your trailer or tow vehicle. Terminals may be specifically called for during the installation of certain electrical devices, but in general, they can be used for any number of electrical connection applications using the appropriate size screw or bolt. They offer a more secure mount and a better connection than a bare wire alone. One of the most common ways an electrical terminal is used is in making a ground connection for a connector or other electrical component.
