Vesper Rope

Marlow’s New Arb Climbing Rope “Vesper” Offers Low Profile, Easy Threading

New for 2022, Vesper is an 11.8mm lightweight tree-climbing line available in two bright colour combinations – orange & blue or lime & purple – for good visibility and safety. Vesper’s 100% polyester construction (24 plait polyester cover over a braided polyester core) provides low elongation with excellent friction and heat resistance.

Vesper is available in a wide range of lengths and can be manually spliced or purchased with a low-profile splice termination. Its unique slim termination design creates an easy thread with the latest mechanical devices on the market, such as the ZIGZAG® by Petzl.

Vesper joins a family of CE EN 1891 Type A certified tree climbing ropes in a range of diameters to suit a wide variety of climbing styles and mechanical climbing devices.
