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” / 11.8mm), and the line's working elongation should not exceed 7% at 540 lb load.

drenaLINE 11.8mm meets ANSI Z133-2017 standards, so long as the user has been trained in the use of smaller diameter lines.

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

“Runs super smooth in petzl ID-S and also is super controlled with my rope wrench and hitch climbing system. I have two other ropes that are a bit quick for me but I am a larger climber (220 lbs). Great rope, feels super sturdy, hands and knots well. Waaaaaay better then I expected. WesSpur as always on point with the deliveries super fast.”

“ Smooth as butter! Have been using this rope for a short time now and loving it. Sheath is tight and works well with Unicender and Compact Bulldog Bone multicenders (tried Kernamster but found it too small/slick for those devices- spooky!). This rope pulls through the canopy very well. SRT only so no MRT report but expect it would work very well for that as well. Rope is somewhat stiffer than double braid but tying mid-line butterfly is no problem. So far very happy with it! ”
