ISC Rope Wrench Single Tether

Description

The ISC RT270B1 Single Leg Tether forms a critical part of the Rope Wrench system. It controls device positioning on the rope and stabilises friction during SRT climbing.

Built for Rope Wrench setups, this tether manages how the device engages with the climbing line. It smooths out ascent by reducing friction and adds controlled resistance on descent. The result is consistent, predictable movement through the tree.

Construction uses 8mm high-strength cord with a durable, abrasion-resistant sheath. The design handles repeated loading, contact with bark, and regular rigging abrasion without quickly degrading.

A rubber grommet sits at the termination point. This keeps the Rope Wrench correctly oriented on the rope. Without it, the device can drop too low or sit incorrectly, which reduces efficiency and control. With the grommet in place, alignment stays consistent throughout the climb.

Rated strength reaches 24kN. That places the tether firmly in professional-grade equipment standards for SRT systems. It is intended for use only as part of a complete Rope Wrench setup and not as a standalone life-support element.

Compact construction reduces clutter at the hitch point. Less bulk means fewer snags and smoother movement through tight canopy sections. That improves efficiency when working through complex branches or long vertical climbs.

SRT systems rely on controlled friction, not static load sharing. This tether plays a direct role in that balance. It helps the Rope Wrench transition smoothly between free movement and controlled engagement.

Designed for daily professional use, the RT270B1 suits arborists who depend on Rope Wrench systems for work positioning and access climbing. It performs consistently under repeated use in demanding environments.

Choose the ISC RT270B1 when you need accurate device control, clean rope management, and reliable SRT performance without unnecessary complexity.
