ISC Squirrel FLEX Tether



NOT FOR PRIMARY LIFE SUPPORT Finding the right balance between the flex and rigidity of the Wrench Tether has baffled developers for some time. Finally, the ISC Squirrel FLEX Tether may well have found that balance. The ISC Squirrel FLEX is made from a high-quality kernmantle rope with sewn eyes, over-moulded with an advanced Polymer, selected to create a rigid tether that allows just the right amount of flex to satisfy tree climbers. In addition, the contrasting stitch pattern of the connecting eyes allows visibility for easy inspections. Finally, the Squirrel FLEX includes the hot forged KL100 accessory karabiner providing a direct connection between your chest harness and your SRT system.
