Teufelberger drenaLINE 11.8mm Climbing Line

Teufelberger drenaLINE is an 11.8 mm 24-strand arborist climbing line built for everyday MRS and SRS work. It has a firm, round profile that holds hitches well and runs predictably through mechanical devices.

How drenaLINE handles

An 11.8 mm line sits in the middle of the common arborist range, which means it works with most friction hitches and many mechanical devices rated for lines around that size. The 24-strand cover is tightly braided, so it resists picking up bark and sawdust and keeps a round shape under load.

That firm hand makes it predictable: your hitch grabs and releases the same way from the first climb of the day to the last. Always confirm that any mechanical device you use is rated by its maker for this diameter and construction. Browse more 24-strand climbing rope to compare.

Climbers who split time between pruning and removals often like a line in this size because it is easy to grip on long descents and holds up well to the extra wear of spar work.

Care and inspection

Keep the rope in a bag away from fuel, bar oil, sharp tools and sunlight. Wash it gently as the manufacturer allows and let it dry out of direct sun. Never step on it or let it drag through grit.

Run the rope through your hands before each climb and look for cuts, glazing, flat spots and core showing. Retire it when in doubt. Life-support gear must meet the applicable standard, be used per ANSI Z133 and the manufacturer's instructions, and be inspected before every climb by a trained user.
