Ultralight Ring Hanger

An innovative new type of ring hanger.
Perfectly combining a rappel ring with a hanger.

Inside diameter of the ring is 32mm, as big as a normal rappel ring, resulting in good maneuverability.
Due to having enough space for a spanner, it can be placed as easily as a normal hanger.
Designed for multi day expeditions, when weight matters.

Climbing Taiwan's results and comments for the 8 mm size:
RESULTS: (from only having 4 new hangers to test):
Tensile Test*: New hanger 26.86 kN, reused hanger 25.03 kN
Tension Test w/ bolt: 22.55 kN
Shear Test w/ bolt**: 24.51 kN, 23.98 kN, reused hanger 26.15 kN
Eye Test: reused hangers 34.98 kN & 35.87 kN

Climbing Taiwan's Break Test

*More noticeable plastic deformation began around +3 kN, so you'd have to decide if this is something you're OK with or not. The hanger is still plenty strong though.
**So here's the thing with 8mm (5/16") stainless steel wedge bolts. In our 35+ tests of this size bolt, we typically get a range of 22 to 28 kN, with more results sitting in the 24 kN range; and in special cases with a ring nut pulling in tension we've even got 31 kN. Because of this, some other hanger manufacturers for example, will rate their 8mm hole hanger more conservatively to 22 kN. So even though the 8mm hanger is rated to 24 kN, it is really only as strong as the bolt you are using it with.
***You could however get about 30 kN by using a 10mm sleeve bolt which uses an 8mm hex bolt (solid shank), but you'll need to drill a 10mm hole instead.

Factory Seconds (Over-Weld) - These Rings are ULTRA-WELDED! To the point it may be slightly difficult to tightly secure a washer. The weld point that attaches the ring back to the plate has a weld that runs a bit higher than intended. Still safe to use, but may need a smaller washer or none at all. Each weld varies.  They work just fine with 8mm Lappas bolts as the nut and washer are super small enough.
