Description
Built for modern arborists. Fine-tuned for control.
The ISC APEX Rope Wrench is purpose-built for professional tree climbers using SRT (Stationary Rope Technique). Designed to manage friction during ascent and descent, it offers a smooth, efficient experience that’s become a trusted part of advanced climbing setups.
With an adjustable cam that allows you to fine-tune friction settings to suit different ropes (11–13mm), the APEX removes the need for tools or guesswork. The swing-open side frame makes mid-line attachment fast and glove-friendly, while the double-lock closure delivers security you can feel, complete with a click you can hear.
Whether you’re pruning at height, performing canopy work, or moving efficiently through the crown, the APEX is engineered for professionals who want more precision in their climb.
Key Features
Adjustable Cam: Choose from multiple friction settings to suit rope type and diameter (no tools needed).
Swing-Open Side Plate: Quick, mid-line access even with gloves on.
Double-Lock System: Audible click confirms secure closure.
Lightweight & Durable: 177g anodised body designed for field longevity.
Certified for Arborist Use: CE-certified as part of an approved SRT kit.
Compatible: Works with ISC tethers, including the Squirrel FLEX.
Specifications:
Rope Compatibility: 11–13 mm diameter
Working Load Limit: 120 kg
Weight: 177 g

Why Arborists Choose the APEX:
The APEX builds on the legacy of ISC’s original Rope Wrench — with added precision, convenience, and compliance. If you’re climbing with stationary rope, it’s not just a tool. It’s a standard.
