Technical Details

I acquired my Russian copy of Petzl Shunt from John E. Weinel, Inc. in 1990.

The Russian copy of Petzl Shunt is 109 mm. tall, 59 mm. wide, 74 mm. thick, and weighs 203 g. This ascender uses a stamped aluminum frame that wraps around one or two ropes. A milled aluminum lever is mounted in the center of the frame, and can be pulled through the back of the frame to allow rigging the rope. The lever is spring loaded so it will automatically return to the operating position. A 9.5 mm. round pin passes through the lever. In use, it presses the rope into a slight detent in the frame. There is a small hole in the back of the lever that one can attach a small cord to to allow remotely releasing the device. bent steel straps on each side of the frame provide some support for the frame and the bolt that serves as an axle for the lever.

There are no markings on this device.

Comments

This is a Russian copy of the Petzl Shunt. The lever is milled instead of forged aluminum, and the machining marks are evident. The side plates are steel, and mine have rusted in storage, corroding the bolts as well. You can see the in the photos. Still, this shunt appears to be as usable as the original.
