NEMA 1-15P & 5-15P - .043" Mold Line Thickness

Lower material content makes for a less expensive UL Approved Blade!

  • Heyco Padded Blades are far less expensive than their Full Thickness counterparts, yet they are functionally equivalent.
  • Thinner gauge material lowers cost, yet full pad configuration meets UL power cord requirements, including UL 1659.
  • All Heyco Padded Blades feature a 90° “knee” section for strain relief and assembly orientation.
  • For overmolding, Padded Blades must be side loaded due to their shaped profile.
  • Series 112 Padded Blades feature a flow-through hole below the mold line for strain relief pull out protection.
  • Series 112-8 Padded Blades feature an extended 90° knee for additional strain relief.
  • Series 103 Polarized Padded Blades are the “heavier duty, full width designed” choice among these lighter duty blades for 18-14 AWG conductors.
  • Series 103-N Padded Blades are both heavier duty and notched to meet high temperature pull out requirements.
