Arbpro Gemini Foot Ascender
Innovative, Compact Knee Ascender for Efficient Rope Access
The Arbpro Gemini Foot Ascender (Gemini Knee) is a smart evolution of traditional knee ascender systems, designed to improve efficiency, comfort, and reliability during rope ascent. Instead of relying on an external bungee cord, the Gemini features a powerful integrated steel spring that automatically retracts and releases the rope, creating a cleaner, more compact, and energy-saving climbing setup.
Built for Safety and Rope Care
A built-in locking mechanism prevents the rope from accidentally slipping out of the device, enhancing safety during ascent. The ascender’s rounded, rope-friendly edges reduce wear and friction, making it suitable for frequent professional use.
Universal Fit and Easy Integration
The Gemini Knee attaches easily to a chest harness via a carabiner and can be fixed to footwear in two ways:
-
Using the EZ-Loop system found on all Arbpro shoes
-
Using the adjustable standard foot loop (included)
With both attachment options supplied, the Gemini is compatible with all common climbing shoes, making it a versatile choice for arborists who want flexibility without compromising performance.
Lightweight, Compact, and Energy-Saving
Weighing just 250 g, the Arbpro Gemini Foot Ascender adds minimal bulk while significantly improving ascent efficiency. Its streamlined design keeps the system tidy and unobtrusive, ideal for long climbs and technical work positioning.
