Fusion Climb Perfect Tension Aluminum Large O-Ring

Beautiful. Priced right.

Steel is heavier than aluminum climbing gear, and I prefer steel over aluminum, as steel is a stronger metal. I would not using this aluminum Fusion ring to climb or rappel, but would use it only on a gear line when working on cutting tree branches when I need to climb. It's seems perfectly safe and suitable for that purpose. I use a Fusion Alloy steel D carabiner that has a 50 Kn Body 3600Lb Gate rating, and meets ANSI Z 359.1 standards. I know aluminum alloys are the industry standard, but I will only hook up a steel carabiner to my climbing harness. Never use a carabiner rated less than 22kN.

This ring works great for a tie out rope for a very large (>150 lb) dog! Now he can get exercise even if I'm not at home to walk him, or if I don't have the time to run with him before going to school.

This is exactly what I needed for rigging my aerial arts sling

Had bought these to hang Clark Jungle Vertex hammock. The attached cords from this hammock are thick, rigid and plastic. Does not work with these rings. However, the Rings are great, work fine on any paracord and assuming climbing rope that's more flexible.

Overall, these rings work fantastic for slacklining.A word of caution:These are aluminum, not steel. Aluminum is a much softer metal and will develop small dents and dings from heavy use with carabiners. These small dents can have sharp edges that may cut or damage your slacklines over time. I strongly recommend getting line sleeves to protect the longevity and quality of your slacklines. I also use small metal files when necessary to smooth out any sharp nicks.That said, these rings are light and travel well in my pack. I'll definitely buy more in t he future.

These rings are of good quality and are great for intended use

Perfect O rings for tying an aerial hammock!
