Sirius 8mm Loop Prusik with Aluminum Ring

The Sirius 8mm loop prusik with ring is a ready-made hitch loop with an aluminum ring captured at one end, so a carabiner or a rope tool can connect to a smooth bearing surface instead of directly onto cord. It suits climbers who want a quick, tidy hitch on a lanyard or a backup on a climbing line.

Where a ring loop prusik fits

A loop prusik is the simplest hitch there is: wrap it around the host rope, pass it through itself, and clip in. Adding an aluminum ring gives the carabiner a round, smooth surface to ride on, which spreads the load and cuts down on the cord wear you see when a carabiner sits directly on the loop.

Climbers use these as adjusters on a rope lanyard, as a backup hitch while they set up, or as a grab point when building a quick haul. An 8 mm cord holds well on many 11 to 13 mm arborist lines, but the bite changes with rope construction, so test it low on your own rope before you rely on it.

Because the ring is already in place, there is nothing to splice or sew. Keep a spare loop on the saddle so you can swap out a glazed adjuster mid-job or add a quick backup while you reset a tie-in point.

Checks before you climb

Inspect the cord for glazing, cuts, and hard or flattened sections, and look at the ring for nicks or grooves worn by the carabiner. A hitch that has slipped under load should be retired, because the heat can damage the fibers inside. Compare other cords in our hitch cord section.

Life-support gear must meet the applicable standard (ANSI Z133 and the manufacturer's instructions), be inspected before every climb, and be used only by trained climbers.
