Heyco® Original Strain Relief Bushings | Pigtail



These Pigtail type Original Strain Relief Bushings have an integral nylon spring and are ideal for use with flat and round cables.

• 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 the 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
• Mounting Hole Plug (PLB240) can be used to fill blank / unused mounting holes and thus allow for a single panel design for multiple applications
