ARMBURY WESEN Prusik Loop for Arborists

The ARMBURY WESEN Prusik Loop is designed for arborist applications, with a 50% aramid and 50% polyester blend that provides heat and mechanical resistance. Available in 8 mm and 10 mm diameters with 50, 60 and 70 cm length options, it lets you choose the dimensions required for your compatible rope system. Minimum breaking strength is 25 kN for the 8 mm loop and 27 kN for the 10 mm loop.

Built for demanding tree work

When preparing your arborist equipment, selecting the right prusik loop starts with material, dimensions and system compatibility. WESEN combines aramid and polyester for resistance to heat and mechanical wear, with six size combinations to suit different compatible setups. Its loop format provides an alternative to an eye-to-eye prusik sling.
