Rappel ring

Three rings previously used as anchor rings. Two are manufactured specifically for that purpose.

A rappel ring is a solid metal ring intended to serve as an anchor ring as an alternative to a quick link.

Advantages

Wider

Most rappel rings are wider than commonly-used quick links and therefore make rope pulls easier by reducing the bending resistance of the rope by increasing the rope's bend radius around the anchor ring.

Lighter

Rappel rings are commonly made of aluminum, so they can be much lighter than similar quick links.

Disadvantages

No gates

Because rappel rings have no gates, anchors must be constructed carefully and incorporate the rappel ring during construction rather than constructing the anchor first and then attaching a quick link.

Soft metal

Rappel rings are usually constructed from aluminum rather than steel, so they are more susceptible to rope groove damage from ropes with debris on their sheaths being pulled through the rings. This is a particularly large problem in sandy areas where rope sheaths act like sand paper and quickly wear away any aluminum they are drawn across.
