HAAS VELOX ASCENT SYSTEM

The Weaver HAAS Velox is a knee ascent system. Paired with a standard foot ascender, it lets you rope-walk with both legs. A double-tube design holds 30 in of in-line bungee inside the unit, so there's no setup and multiple users can share it without adjusting. The bungee runs over a stainless sealed-bearing sheave in a machined aluminum block and can be replaced in under five minutes without tools.
