A durable steel ring for friction savers, anchors, and redirects.
The Climbing Technology steel ring is a durable connection ring that arborists use in friction savers, anchors, and redirects. Steel holds up to rope wear better than aluminum, which matters for gear that sees rope running over it all day.
Rings show up all over a climbing setup: the ends of a friction saver, anchor points, and redirects. When rope runs over a ring repeatedly, aluminum wears grooves faster. Steel lasts longer and handles abrasion better, at the cost of a little extra weight.
Compare it with other climbing rings to choose size and material.
On a friction saver, the ring takes rope wear every time you advance or descend. A steel ring lasts much longer under that kind of use, and it is less likely to develop the sharp grooves that can damage your climbing line.
Steel rings also work as anchor points for redirects and as connection points in rigging setups where you want a simple, durable piece of hardware that will not wear out quickly.
Check the rating and the maker's instructions before putting the ring into service. Use it only in configurations the maker approves.
Before each climb, look for grooves, cracks, rust pitting, and sharp edges, and retire the ring if you find any. Life-support use must follow ANSI Z133, the manufacturer's instructions, and your training.
Store it dry to prevent rust, and keep it away from chemicals. Wipe it down after wet or sappy climbs, and do not apply oils or coatings unless the maker approves them for use with rope.

Steel wears longer and resists abrasion. Aluminum is lighter. Choose by how much rope runs over the ring.
