3M™ Highland™ Vinyl Insulated Butted Seam Block Fork is a lug connection terminal that ensures an ideal fit while offering reliable and safe performance. The terminal has a vinyl-insulated, butted-seam barrel and withstands temperatures of -40 to 221 degrees F (-40 to 105 degrees C). Electrolytic copper construction offers good conductivity and a tin-plated finish resists corrosion. 3M™ Highland™ Vinyl Insulated Butted Seam Block Fork is color-coded for quick and easy identification of the wire size required. It has a butted-seam barrel that is covered by a funnel-designed, rigid-molded, polyvinyl chloride sleeve to guide the wire into position while providing electrical contacts and mechanical stress relief at the point of insulation. The abrasion-resistant, flared, vinyl-sleeve insulation ensures easy crimping. UL Listed, CSA Certified and RoHS 2011/65/EU Compliant.
