  • Metal spring eases the cable into a lazy bend, which prevents sharp bending and assures longer cable and product life.
  • Protects the lifeline of your electric/electronic products by absorbing the forces of push, pull, twist, and flex.
  • Securely anchors, insulates, and protects cable at panel entry points.
  • Not recommended for applications where the power supply cord is subject to whipping or "jump rope" type motion.
  • Part No. 1914 may be used with either spring style.
  • Fill blank/unused mounting holes with Heyco Double D Plugs.
