Ultra Vee

Ultra Vee climbing rope from Teufelberger is a premium rope for professional tree care, also known as Braided Safety Blue. This 16-strand rope is certified according to EN 1891A and ANSI Z133-2012, with a unique blue polyamide safety core that clearly indicates when the rope's sheath is damaged and it's time to replace the rope.[1][5]

Construction and Materials

Ultra Vee has a core of parallel twisted blue nylon (polyamide) yarns that keeps the rope round and stable under load. The sheath consists of a 16-strand braid of tightly twisted polyester over polyolefin, treated with a protective coating that minimizes wear, improves durability, and provides optimal grip. The rope is easy to splice and is available with a tight eye splice.[1][5]

The 12.7 mm diameter provides a comfortable handle that reduces fatigue and increases efficiency when working in trees.[1]
