Entirely legal to FIE and USFA standards, and like our econo two prong cord, this is excellent value and quality. What makes this ‘super’ is the superior build and quality of the econo cord added to the transparent wire insulation for easy visual inspection of the cord. Unlike many other economy priced body wires, our alligator clips, for example, are both soldered and screwed, while our plugs are held into place by metal wires rather than breakable plastic clips and held German style in place. Highly conductive heavy gauge wires reduce breakage, especially near the end plugs where cord twist is common. Pins are equally superior, with overlapping layers for better conductivity and durability, giving solid contact. Please note, color of plugs may vary from picture.
