Aluminum Prusik Snap Lanyard Adjuster

An aluminum prusik snap lanyard adjuster is a snap hook used to connect a prusik or other friction hitch on your positioning lanyard to your saddle. The aluminum body keeps weight down compared with a steel snap.

How a prusik snap works

With a prusik-style adjuster, a loop of hitch cord is tied around the lanyard rope and clipped to a snap that goes on your saddle D-ring. Load it and the hitch grips; push it along and it slides. The snap is the link between that hitch and your saddle, so it needs a secure gate and a smooth eye for the cord to sit in.

Aluminum keeps it light, which you notice when you are carrying a full rack all day.

Inspection

Check the gate closes and locks fully, and look for grooves or sharp edges where the hitch cord bears. Aluminum wears faster than steel under rope, so retire it if it develops a groove. Replace the hitch cord when it glazes. Compare mechanical options in rope grabs.

A prusik snap is also a handy upgrade if you have been running your hitch on a plain carabiner. The snap sits on the D-ring more naturally and keeps the hitch loop oriented as you lean back, so the hitch tends to grip and release more consistently.

Make sure the snap's eye and gate are compatible with the hitch cord diameter you use. Too small an eye can pinch the cord, while a snap that is too big for the D-ring can sit at an awkward angle and load poorly.

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.
