Version A

Technical Details

Olivier Peron Caillet sent me this New Alp Ring in 2008.

The New Alp Ring is an anodized aluminum torus with a D-shaped cross section, with the flat surface on the outer diameter. The Ring has a 55 mm. o.d., 40 mm. i.d., and is 10 mm. thick. Mine weighs 27 g.

There are no markings on the ring.

Comments

The Ring received French Patent #2,767,484, "Accessoire pour l'alpinisme transformant tout descendeur en huit en descendeur autobloquant," with the applicaton submitted on August 25, 1997.

According to the instructions, the Ring is used to allow rappelling on doubled 8.5 mm. ropes with a Figure Eight. The instructions say to clip into the rope hole (the large hole) on your eight, and then pull a double bight through the eight’s eye and then through the ring, and secure it with a single locking carabiner. If the ring is larger than the eight's eye, then the carabiner can pivot on the ring. The rappeller presses down on the end of the carabiner. If the rappeller releases pressure, the carabiner rotates, providing an autostop function. Unfotunately, this requires a "negative action" that I dislike for well-known reasons.

Technical Details

I acquired my New Alp Ring, Version B in 2017 as part of Bob Thrun’s collection.

Version B is an anodized aluminum torus with a D-shaped cross section, with the flat surface on the outer diameter. The Ring has a 44 mm. o.d., 32 mm. i.d., and is 11 mm. thick. Mine weighs 20 g.

There are no markings on the ring.

Comments

Version B is smaller than Version A, and there are quite a few eights that this version might work with. For example, it fits the CMI quite well.
