Teufelberger 8mm Ocean Polyester Thimble Loop

The Teufelberger Ocean Polyester thimble loop is an 8mm polyester prusik loop with a thimble that protects the eye where it meets hardware. Climbers and riggers use loops like this for friction hitches, short tethers, and attachment points.

Where a thimble loop fits

A thimble keeps the eye of a loop open and gives a carabiner a smooth, hard surface to bear on. That cuts wear at the point where soft cord meets metal, especially on a loop that gets clipped and unclipped all day. An 8mm polyester loop is a handy size for prusiks on rigging lines, a short attachment for a pulley, or a backup hitch.

Polyester stretches little and stands up to abrasion, which suits these jobs. Compare other cords and loops in our hitch cord and split tails.

Rigging crews use short loops like this to attach a pulley or block to a sling, or to tie a prusik onto a lowering line for a mechanical advantage setup. Having a few spares in the rigging bag saves time on the job.

Use within limits

An 8mm loop is not a substitute for a climbing hitch cord unless the maker approves it for that use with your rope. Check the rated strength, test any hitch on the ground first, and never exceed what the loop is rated for.

Inspect the cord, the thimble, and the splice or stitching before each use. Retire it after a shock load or if you find cuts, glazing, or a deformed thimble. Follow the maker's instructions and ANSI Z133 practice.
