Each strain reliever protects the lifeline of your electric/electronic products by absorbing forces of pull, push, twist, and FLEX.
These strain relievers are not recommended for applications where the power supply cord is subject to whipping or "jumprope" type motion.
Pigtail strain relief fasteners add reliability, longevity, and safety. These strain reliefs will pass CSA's 50,000 cycle "vacuum cleaner" test (C22.2 No. 67).
Each Pigtail strain relief fastener securely anchors, insulates and protects cables at chassis entry points.
Integral nylon spring on each nylon fastener or separate metal spring eases the cable into the lazy bend, prevents the strain of sharp bending and assures longest cable and product life.
These strain reliefs standardize panel design! Fill unneeded SR mounting holes with Heyco Double D nylon fastener Plugs.
