Sidewinder Is it a swivel or is it a captive eye connector? In fact, it's both. The Sidewinder is a directional connector with an integral swivel. Essential in applications when there is a need to manage spin, rotate the load relative to the anchor or simply to minimize lanyard tangles. The Sidewinder is often used as a connector on guided fall arresters as it can be captive on a system, allows rotation by the user and is quick, easy and secure when connected.
