[ Top | Version B | Return to Figure Eights ]
I acquired this figure eight from On Rope 1 at the 2000 NSS Convention.
The Stubai, Version A is forged from aluminum alloy and then soft anodized. Mine is 139 mm. tall, 74 mm. wide, and 12 mm. thick. The rope hole is 49 mm. high and 49 mm wide. The top center thickness is 12 mm. The shaft length and width are 44 mm. and 26 mm, respectively. The eye measures 24 mm. by 24 mm. My eight weighs 110 g.
One side is etched "STUBAI" and "99005310." The other side has a raised forged icon showing how to rig the eight, with up- and down-pointing triangles labeled "KN 35."
CommentsThe Stubai, Version A is a typical example of a full sized, forged, aluminum figure eight. Other than this, the curves are smooth and the eight works nicely.
I
used to laugh at rigging icons on eights, but a day after buying
this eight, someone showed me an advertisement for an investment
firm that had a climber rappelling on an eight rigged as shown
on the right. I won't invest with that firm!

I acquired this eight used from Marcus Warme in 2005.
The Stubai, Version B is forged from aluminum alloy and then soft anodized. Mine is 129 mm. tall, 81 mm. wide, and 14 mm. thick. The rope hole is 41 mm. high and 50 mm wide. The top center thickness is 11 mm. The shaft length and width are 49 mm. and 24 mm, respectively. The eye measures 19 mm. by 28 mm. My eight weighs 97 g.
There is a small projection on one side of the upper loop with a 5 mm. diameter hole for attaching a keeper sling.
Version B has "STUBAI" stamped on one side and "KG.2000" forged in raised letters on the other.
The Stubai, Version B is a typical example of a "midi" size, forged , aluminum eight with a keeper cord hole. The keeper hole is not in a good place, since the keeper can easily get entangled with the main line, but where else could it be? If it were on the shank or eye, then the keeper would prevent rigging the eight while the keeper was attached to the user. The is essentially identical to the Kong "8" Light Plus, Version B. The Camp/Lowe Fungo and Salewa have similar keepers attached on the rope loop as well.
The Stubai, Version B is lighter than most figure eights. The compact design causes the rope to make sharper bends, providing more friction on stiff ropes than a full-size eight. The eye could probably be used for belaying.
