Butted seam-construction prevents splitting under maximum pressure. Internal barrel serrations grip wires tightly to resist pull-out and reduce electrical resistance. Tin-plated brass construction for corrosion resistance. Wire range stamped on metal surface for easy interpretation. Shouldered barrel insulation quickly positions terminal for proper crimping. Expanded insulation entry accommodates a wide variety of insulation diameters and provides additional insulation support Color coded for easy identification. Funnel entry on disconnect terminal quickly guides wires into crimp barrel and eliminates turned-back strands.
