12mm (1/2”) • 12-strand • 6,000 lb ABS • 3% elongation at 10% ABS • 6.8 lb per 100' • sewn eyes only

One of the first lines ever designed specifically for arborists, Arbor-Plex 1/2” remains one of the most economical ropes on the market. In the 1/2” diameter, has a breaking strength of 6,000 lb. and is rated as a climbing line. At 6.8 lb. per 100 ft., Arbor-Plex is one of the lightest climbing lines we sell. Arbor-Plex is a 12 strand single braid rope with a polyester cover surrounding polyolefin fibers in the center, making it abrasion resistant as well as lightweight. It is a great choice for wet climates where mildew and rot can be a problem.

Arbor-plex is also available in larger diameters for use as a rigging line. See Arbor-Plex rigging line here.

ANSI Z133-2017

The American National Standards Institute (ANSI) has released the ANSI Z133 safety requirements which apply to arboricultural operations.

Arborist Climbing Ropes are required to have a minimum breaking strength of 5,400 lb (24 kN) when new, and should be no smaller than 1/2” (12.7mm) unless the employee has been trained in the use of smaller line (down to 7/16” / 11mm), and the line's working elongation should not exceed 7% at 540 lb load.

Arbor-Plex rope meets ANSI Z133-2017 standards.

The full ANSI Z133 safety requirements are available on our tree care standards page.

Rated: Good Review by: Robert

“Strength is great, not real great for a Petzl zig zag. After 15-20 uses the rope is squarish under load and does not feed well on the descent. Ascenders work fine on it. ”
