The canyon descender ATK has been developed by the French canyoneer Jean-Claude Schiavinato and has been brought to the market after several try-outs and prototypes.
The ATK-D is similar to the ATK in its braking functions, but the ATKD has been optimized to be positioned at the relay, as a belay device
 
ROPES: Ropes from 8.5 to 12 mm
 
MANUFACTURING: Mass-machined, French manufacture. Designed and manufactured in Toulouse, FRANCE
 
ANTI-ROTATION CARABINER: The shape of the attachment point prevents rotation of the carabiner and thus makes it possible to use it as a belay device
 
STOP KEY: blocking knot stops fast, simple and easy to inspect. Gradual tension recovery thanks to the braking possibilities
 
The advantages of ATK:
Simple and efficient to use
Easy to use with double ropes, also easy to brake/block your descent on double rope.
The upper jaw facilitates the management of the braking power without the risk of rope skipping
The lower jaw is enlarged in order to easily separate the double ropes
The shape of the ATK was refined to give users good control over the flow of the rope during descent
