The Squirrel FLEX Tether is designed to work with Rope Wrench SRT systems, helping maintain clean alignment and efficient movement during ascent, descent and work positioning.
Rigid with the Right Amount of Flex
The advanced polymer over-moulding creates a rigid tether with controlled flexibility, helping the Rope Wrench remain correctly positioned while still allowing natural movement through the climbing system.

Built from high-quality kernmantle rope, the Squirrel FLEX Tether offers excellent handling, durability and reliability for demanding professional tree climbing applications.
Snug Sewn Eye Design
The sewn eyes are designed to hold the karabiner securely, helping reduce unwanted movement and providing an optimal connection to the Rope Wrench.
Inspection-Friendly Stitching
Contrasting stitching improves visibility during routine checks, helping users inspect the tether more easily as part of their climbing equipment maintenance.
