  • Integral nylon spring eases the cable into a lazy bend; prevents sharp bending and assures longest cable and product life.
  • Adds reliability, longevity and safety. Will pass CSA's 50,000 cycle "vacuum cleaner" test (C22.2 No.67).
  • Protects the lifeline of your electric/electronic products by absorbing forces of pull, push, twist, and flex.
  • Securely anchors, insulates, and protects cables at panel entry points.
  • Not recommended for applications where the power supply cord is subject to whipping or "jump rope" type motion.
  • Fill blank/unused mounting holes with Heyco Double D Plugs.
