3M™ Scotchlok™ block fork terminal 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, seamless brass sleeve to guide the wire into position while providing electrical contacts and mechanical stress relief at the point of insulation. The abrasion-resistant, flared, nylon-sleeve insulation ensures a positive grip and has a stepped design for mistake-proof crimping.
