The New HAAS Velox makes the original system even better. With an additional 18 inches of bungee in the system, the HAAS Velox is a one size fits all, zero set up, efficient rope ascent tool. 30 Inches of usable bungee extension eliminates any set up, as well as “dead spots” in the return action. Made in Ohio by the guys at Haas Tree Gear. The bungee is terminated at the top of the HAAS Velox, travels down though a channel to the bottom where it is wrapped around sealed stainless steel bearings inside of a machined aluminum block for minimum friction. It then returns back up a second channel where it is tied to the snap. The result is 31 inches of inline bungee are contained in the system at rest, allowing 30 inches to be extracted under load. Bungee is replaceable in under 5 min with no tools. Makes SRT Climbing an absolute breeze.
