You'll make your job easier with these 3M Scotchlok Color-Coded Ring Tongue Terminals. The polyvinyl chloride sleeves are shaped like funnels, so wires insert easily to the right position every time, and the butted-seam barrels hold them securely for dependable performance. Youll get great conductivity out of the electrolytic copper construction and corrosion resistance from the tin plating. These yellow terminals work reliably under temperature conditions from -40 to 221 degrees F (-40 to 105 degrees C), and they're rated 600V for building wire and 1000V for signs, fixtures and luminaires. They're also UL Listed, CSA Certified and RoHS 2011/65/EU Compliant.
