Technical Details

Artyom Babin (Артём Бабин) sent me this Sinto in 2022. The Sinto is 108 mm. tall, 56 mm. wide, 78 mm. thick, and weighs 187 g.

This Sinto is 108 mm. tall, 58 mm. wide, 78 mm. thick, and weighs 187 g. This ascender uses a stamped aluminum frame that wraps around one or two ropes. A forged 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 plated 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. The shell and lever are painted black.

There are no markings on this device.

This is a Russian copy of the Petzl Shunt. It closely resembles the Boris Laptev Борис Лаптев) except that the lever is not milled.
