I acquired this eight from Ural Sport in 2004.
The Ural-Alp (Урал АлЬп) Self-Braking Descender/Belay Device is made from two pieces of nickel-plated aluminum, screwed together. Mine is 130 mm. tall, 65 mm. wide, and 29 mm. thick. The rope hole is 33 mm. high and 41 mm. wide. The top center thickness is 28 mm. The shaft length and width are 44 mm. and 15 mm., respectively. The eye measures 16 mm. by 16 mm. My eight weighs 79 g.
One plate is stamped " "RUSSIA" and "URAL ALP," and the other is stamped "KOZLOV DESIGNS."
The
two-plate design allows one to use the device as a normal figure
eight, or to add an auto-stop capability by rigging the rope between
the plates. In the latter configuration, the rappeller must hold
the free end of the rope up to keep it from wedging between the
plates. This can be tiring if the rope weight is heavy - which
it shouldn't be for this class of device (no long rappels!). The
original version did not have ears, but the designer quickly
realized that adding small ears made for a better device, and
created an eared Version B.
The screws do not support a significant load, and even if they fail, the rope will remain rigged and will hold the plates together.
The manufacturer provides an ultimate strength rating of 20 kN. The device is designed for 9 to 11 mm. rope.
The Ural-Alp Self-Braking Descender/Belay Device, Version A is lighter than most figure eights. The rope hole is shorter and narrower than normal, so it may provide too much friction on stiff or muddy ropes. The eye is too narrow to accept two full size locking carabiners.
Since the Ural-Alp Self-Braking Descender/Belay Device is made
of thin plates, the edges may sharpen as they wear. Beware of
this, and file them smooth if this should occur.

Hundreds of cell phone users complained and asked me to for a simpler, mobile friendly site. In particular, they wanted me to limit each page to a small number of pictures and minimize my use of text. This new site provides what they asked for.
