Description Adoption of hard engineering plastics, the wire connectors are wear-resistant and practical for use. Plastic shell molding, interior steel, which has better electric conductivity and better grip the wire, won't fall off easily even with strong vibration. Easy to use, simply strip the wire ends and then inserted into the cap, then pressed with pressure pliers. Features - Color: As shown. - Size: 17.3 x 9.8 x 2.3 cm - Material: Plastic & steel - Installation is easy: Strip the outer skin of the wire, the wire and tighten it. Then insert the rotating terminal and tighten it with pressure pliers. - Broad use: Suitable for all kinds of electrical products, lighting, home wiring and other wiring equipment, reusable, safe and reliable. - Thermal plasticity engineering plastics molding, tough, strong, tightly wound. - Good insulation, not easy to age. - Internal high angle steel, resistance, good conductivity, not easy to loose. - Dear buyer, due to lighting effect, monitor's brightness, manual measurement, etc., there could be some slight differences in the color and size between the photo and the actual item.
