A practical color coded design makes it simple to quickly identify the wire size needed for the 3M™ Scotchlok™ color coded Butt Connector. A rigid-molded, funnel-designed polyvinyl chloride sleeve covers the butted-seam barrel. This innovative construction lets users place each wire where it belongs while relieving mechanical stress and providing electrical contacts at the insulation point. Crimping is simple as a result of this butt connectors flared, abrasion-resistant, vinyl sleeve insulation. This butt connector is UL Listed, CSA Certified and RoHS 2011/65/EU Compliant.
