HARKEN NINJA™ is a light ascender with a unique system of two pressure cams,
which do not have teeth and significantly save the rope during ascent.
This blocking mechanism is based on yacht stoppers ,
which are also used in launch systems such as: ArbPro LD2.
It is therefore intended for the most demanding use with extreme load, where it is necessary to avoid damage to the braid.

Thanks to the opposing pressure of two independent segments
the blocker works in any position and can be used on both the left and right foot.

Duralumin alloy body, while the double cams are stainless steel.
The HARKEN NINJA ascender with max working load of 150 kg.
The cam system is designed with lower spring force to minimize rope drag.
