HAAS Velox Clip - N - Go Knee Ascender

HAAS Velox Clip - N - Go Knee Ascender

The HAAS Velox Clip - N - Go Knee Ascender is designed to provide arborists with a fast, efficient, and highly adaptable knee ascent solution. Built around the proven HAAS Velox system, this version is specifically configured to clip directly into the ascent system foot loop on Clip’N Step boots. Its design focuses on simplicity, smooth operation, and reduced setup time, making it well suited to shared use and dynamic working environments.

Zero-setup and self-adjusting performance

This knee ascender features a zero-setup design that requires no initial adjustment, allowing multiple users to deploy it immediately without reconfiguration. A self-adjusting double tube system houses an in-line bungee that provides over 30 inches of elongation. The snap is positioned just above the ascender, extracting smoothly to remove dead spots in the return action and maintain consistent tension throughout each stride.

Engineered for smooth and efficient ascent

The bungee system is designed to maximise friction reduction during ascent. It terminates at the top of the Velox, travels down an internal channel, and wraps around a shiv fitted with stainless steel sealed bearings housed within a machined aluminium block. The bungee then returns through a second channel before tying off at the snap, creating a smooth and efficient energy return with minimal resistance during climbing.

Durable, versatile, and easy to maintain

Constructed from durable nylon, the Velox Clip - N - Go is lightweight and compact while remaining robust enough for professional arborist use. It can be used in both single rope and double rope systems and is compatible with or without a rope wrench. The bungee is fully replaceable in under five minutes without tools, supporting long-term use and straightforward maintenance in the field.
