I acquired my Proverti CD 302 from Ondřej Belica in 2015.
The Proverti is forged from aluminum alloy and then hard anodized. Mine is 108 mm. tall, 79 mm. wide, and 18 mm. thick. The rope hole is 35 mm. high and 53 mm. wide. The top center thickness is 11 mm. The shaft length and width are 35 mm. and 25 mm., respectively. The eye measures 20 mm. by 25 mm. The ears are 11.8 mm. long. My Proverti weighs 89 g.
The concave side of this eight stamped with "KN25" and printe with "PROVERTI" and "CD 302." The conceave side is printed with "www.proverti.pl."
This is one of the following family of essentially identical "mini" size figure eight with ears:
|Ace||Fusion (Good Makings) Compact Bent 8|
|AMP Outdoor 8||Good Makings, Version B|
|Climb X Mini Rescue 8 With Ears||Mad Rock Small Rescue 8|
|Faders Ballet||Proverti CD 302|
These are small eights, and lighter than most figure eights with ears. If these were flat, they would create more friction than most. The bend allows them to be rigged two ways with differing amounts of friction. Even so, the rope hole is shorter than normal, so these eights may provide too much friction on stiff or muddy ropes.
Other small eights have similar bends. Examples are the Chouinard Version B, Faders, Frendo Version B, Kabelwerk Oberspree (perhaps the original design motivating for all of these - and yet not intended to be an eight at all!), and the Trango Penta, but this eight and its equivalents also have ears. Better yet, the ears are placed low where they can function effectively without increasing the size of the eight. For eared eights, I like this design enough to give each example a star.
