Version A Version B

Overview


The Krok web site documentation refers to this as the Mini-clamp "Stregor." The name "Stregor" (Стрегор) was given in memory of two mountaineers Strelnikov Yuri and Goryunov Nikolay (Стрельников Юрий и Горюнов Николай), who once made similar ascenders.

I acquired my Krok Mini Ascender, Version A from Gear4Rocks in 2012.

This ascender is 35 mm. tall, 62 mm. wide, 28 mm. thick, and weighs 77 g. The shell is stamped from 3.5 mm. aluminum alloy and painted. The rope channel is 14 mm. wide.

The cam is cast from stainless steel. The cam radius increases from 15 to 29 mm. over an angle of 102°, giving a 21° cam angle. The tooth pattern is (2.H.2)^3(2.3.2).

There are no markings on this ascender.

Comments

This ascender is patterned after the Wild Country Ropeman. It is not a conventional ascender by any means, and I wouldn't consider it as the primary ascender for a caving rig. It was designed to be a lightweight ascender for emergency or occasional use. The ascender is placed on the rope by swinging the shell open, pulling the cam open with the cable, inserting the rope, closing the shell and securing it with a carabiner. The slings must be connected to this carabiner. The carabiner keeps the ascender from coming off the rope, but if the ascender must be removed, I recommend clipping the cable to the carabiner so that you do not drop the ascender by accident.

Alex Kostromitinov donated a quite a number of items to my collection, and Alex Dniprovsky, who lives in Toronto, arranged for delivery. I give a hearty "Thank You!" to each of them.
