Description of 3M Scotchlok Electrical 560B BOX Retardant
High performing polypropylene insulation ensures there are no shorts; making it ideal for complex circuits when used for parallel splicing or a tap wire. Makes it simple to connect a tap wire to a run wire electrically via a self sealing and self stripping design. Its design lets you use it with 18 to 16 AWG solid or stranded wire for taps or 14 AWG stranded for runs. Easy conductivity is assured thanks to the brass element construction; and it's plated with tin for powerful corrosion resistance. Use it in buildings with circuits rated up to 600V; or use it with fixtures; signs or luminaires rated up to 1000 Volts for maximum flexibility.
I had a project to connect two wires but didn't want to splice them or cut them with a knife. These little gems got the job done with a click and are great for terminating wires.
