The CC-120 Coax Center Conductor Cleaner from Jonard Tools is designed to clean away excess dielectric from the center conductor of distribution or trunk cables without nicking or scratching the center conductors surface. Unlike other center conductor cleaners on the market that either come with a 'V' blade or a 'straight' blade, Jonard includes both styles with theirs. Blades are easily swapped with 4 phillips screws.
