3M™ Scotchlok™ Color-Coded Closed-End Connector is an electrical crimp sleeve connector with a copper insert that allows for fast splicing of copper conductors. The vinyl-insulated connector is 600V-rated for building wire and 1000V-rated for signs, fixtures or luminaires. It withstands temperatures of -40 to 221 degrees F (-40 to 105 degrees C).

3M™ Scotchlok™ Closed-End Connector is color-coded for quick and easy identification of the wire size required. It allows for quick wire insertion with a smooth, flared entry. The copper insert offers good conductivity. RoHS 2011/65/EU Compliant.
