Arbor-Plex was the first synthetic rope designed specifically for the arborist industry and remains one of the most-used lines today, both as an arborist climbing line and as a rigging line in larger diameters. Arbor-Plex is constructed of a tough polyester jacket around polyolefin center fibers which creates a light, high-strength rope with maximum wear resistance. Samson braids Arbor-Plex to be tighter than other 12-strand climbing lines for extra durability and snag resistance. Newer ropes might be stronger (see ArborMaster®) or lighter (see Velocity), but Arbor-Plex is still an excellent choice for an economical climbing line that you can rely on.

Customer Reviews

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. ”

Safety & Technical Information

ANSI Z133-2012

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

Arborist climbing lines 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 Z133-2012 standards.

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