1、Reliable Works: The insulating ABS housing will prevent non current carrying parts from energizing and won't crack in high abuse applications. Constructed from a single piece of brass to reduce friction and overheating, providing excellent electrical conductivity. 2、Secure Locking: Safety locking design, the plug is tightly locked on the electrical equipment, preventing the vibration from loosening and falling off. Internal wire clips ensure secure wire connection. 3、Plug Protector: Each wire is slid into a separate tube and tightened to prevent short circuit or stray wires. Flexible rubber dust sealing keeps moisture and contaminants out of the wiring compartment. 4、Smart Twisting: Ergonomic grooved design with radial grip ridges is ideal for gripping, turning and pulling. Alignment of facial and body features easy assembly. The grip screws are installed from the same side for easy tightening. 5、Practical Uses: Commonly used in generators, temporary power solutions, transfer switches, welding equipment, RVs, trailers and trailers and camp welding equipment, etc.
