Technical Details

I acquired my left and right Chinese ascenders from Suntek in 2017.

The Chinese is 70 mm. tall, 66 mm. wide, 32 mm. thick, and weighs 98 g. and 131 g. including the supplied harness. The body is stamped from aluminum alloy. Two slots at the bottom and two at the rear provide secure attachment for the supplied harness, and a slot at the front holds the ascender against the foot. A separate stamping helps form the rope channel. The rope channel is 14 mm. wide, and has two rollers to reduce friction. Each roller is riveted between the body and the rope channel stamping. The rollers are 12.9 mm. long, 13.7 mm. diameter, and have a turned U-groove that give the rollers an 8.5 mm. minor diameter.

The cam is cast steel. The cam radius increases from 29 to 50 mm. over an angle of 40°, giving a 38° cam angle. The tooth pattern is (3.4.H.4.2.3.H.2.2.1)(1H1)(4.3). A small projection on the top of the cam provides a thumb tab, and the upper surface is grooved. A small pin on the shell limits how far the cam can open.

Each ascender came with a harness made from 20x1.0 mm. webbing gray webbing. One piece of webbing circles the ankle, another goes under the instep. A two-piece buckle allows for adjusting the strap around the ankle. The strap under the foot is adjusted at the ascender. A piece of tubular webbing under the foot protects the gray harness webbing.

There are no markings on these ascenders.

Comments

This ascender is a copy of the Camp Turbofoot. Foot ascenders such as this don't fit into the climbing systems that I commonly use, although I have met froggers that seem to like them (they also like the frog).
