Heavy duty Paramount cords feature doubly insulated, heavy gauge wire for strength.
Wires within the cords are positioned in parallel to eliminate twisting, knotting, kinking,
and breaking, and they're individually stranded and tinned for maximum conductivity.
Cord coils keep their spring and elasticity through years of use.

Features:

• PC Female: Fits most PC cords. Used mostly for extension and adapter cords. Has
  hollow tube as center contact. (Note: PC Male has pin for center contact).
  
  
• Household Female: Accepts Household male plug. Used on extension and adapter
  cords and with slaves. Can be inserted either way if polarity is an issue.
