Product information & specifications
ISC Chipmunk Flex Tether
Designed for UK arborists, rope-access technicians and SRT climbers seeking a compact, high-performance tether solution. The Chipmunk Flex measures just 9″ (≈225mm) in length, making it significantly shorter than many traditional tether systems — this helps reduce system height and improves reach and efficiency when ascending in tree-work or access setups.
Key Features & Benefits
- Short 9″ (225mm) length: Reduces overall system bulk and improves ascent reach.
- High breaking strength: Rated to 24kN for professional confidence.
- Rigid yet flexible design: Holds its shape for easy clipping while still flexing under load.
- Sewn eyes and central connection point: Gives multiple secure attachment options.
- Lightweight: Adds minimal weight to your climbing system at approximately 105g.
- UKCA / CE / ANSI compliant options: Choose the certification that matches your working region.
