Built around a patented design, the Velox increases bungee travel within the system, supporting fluid movement and consistent return during ascent. Its focus on simplicity and adaptability makes it well suited to professional arborists and rope access users working across varied climbing setups.\u003c\/p\u003e\n\u003ch4\u003eZero-setup system with extended bungee travel\u003c\/h4\u003e\n\u003cp\u003eThe Velox features a zero-setup design that allows immediate use without adjustment, making it suitable for shared equipment and multi-user environments. A double tube system contains a total of 30 inches of in-line bungee, providing over 30 inches of elongation during movement. The snap is positioned just above the ascender and extracts smoothly, eliminating dead spots in the return action and maintaining consistent tension through each step.\u003c\/p\u003e\n\u003ch4\u003eEngineered for smooth, low-friction ascent\u003c\/h4\u003e\n\u003cp\u003eTo maximise efficiency, the bungee terminates at the top of the Velox and travels down an internal channel to the base of the unit. It then wraps around a shiv fitted with stainless steel sealed bearings housed within a machined aluminium block. From there, the bungee returns up a second channel before tying off at the snap. This layout reduces friction and resistance, supporting a smooth energy return and controlled ascent.\u003c\/p\u003e\n\u003ch4\u003eVersatile, durable, and easy to maintain\u003c\/h4\u003e\n\u003cp\u003eThe HAAS Velox Knee Ascender is designed to integrate easily into both single rope and double rope systems and can be used with or without a rope wrench. Its durable construction supports long-term professional use, while the internal bungee can be replaced in under five minutes without tools. This straightforward maintenance approach helps keep the system performing consistently with minimal downtime.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eZero-setup knee ascender for immediate use\u003c\/li\u003e\n\u003cli\u003eSelf-adjusting bungee system for smooth ascents\u003c\/li\u003e\n\u003cli\u003eDouble tube design housing 30 inches of bungee\u003c\/li\u003e\n\u003cli\u003eOver 30 inches of effective elongation\u003c\/li\u003e\n\u003cli\u003eInternal channel system designed to reduce friction\u003c\/li\u003e\n\u003cli\u003eStainless steel sealed bearings in an aluminium block\u003c\/li\u003e\n\u003cli\u003eCompatible with single and double rope systems\u003c\/li\u003e\n\u003cli\u003eUsable with or without a rope wrench\u003c\/li\u003e\n\u003cli\u003eBungee replaceable quickly with no tools required\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Billington Outdoors","offers":[{"title":"Default","offer_id":52685086818647,"sku":"08-98109","price":179.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/0785\/8263\/files\/HAAS-Velox-Knee-Ascender.jpg?v=1769925138","url":"https:\/\/treeworker.com\/products\/haas-velox-knee-ascender","provider":"www.treeworker.com","version":"1.0","type":"link"}
