Sterling 9mm Hitch Cord, By the Foot

Sterling 9mm hitch cord sits between the common 8mm and 10mm sizes, giving climbers a middle option for friction hitches on popular arborist climbing lines. It is sold by the foot so you cut the length your hitch needs.

Why a 9mm cord

A hitch that grabs too hard is tiring to tend; one that grabs too little is dangerous. Going from 8mm to 10mm changes the bite a lot, and a 9mm cord gives you a step in between. Climbers often reach for it when 8mm feels grabby on their line and 10mm feels slow.

Because you buy it by the foot, you can cut a length for a Valdotain, Distel, or other hitch, and finish the ends with knots or have eyes made. Look through other hitch cord and tech cordage to compare sizes.

Testing, inspection, and replacement

Every hitch cord and climbing line combination behaves differently, and a new rope or a wet day can change it. Set up and test close to the ground before climbing, and adjust wraps and braids until the hitch holds and releases the way you want.

A by-the-foot cord also makes it easy to experiment. Cut one length for a Valdotain tresse and another for a Distel, climb on each for a week, and keep the one that suits your rope and style. Write down the length that works so you can cut replacements without guessing.

Check the cord daily for glazing, stiffness, and cover wear, and swap it out at the first sign of heat damage. Hitch cord is life-support gear: use it only in a system that meets ANSI Z133 and the manufacturer's instructions, inspect it before every climb, and get trained before you tie into anything new.
