There is actually some irritation, due to the recommendation for the SpiderJack 3 cams. The informations in our Shop are recommendations only based on tests by the manufacturer, which cam works with which rope.
But it is just a recommendation, because it depends on the wear of the SpiderJack body, the condition of the rope and individual experience/preferences of the climber, which combination works best.
Generally, both cams work with all tree climbing ropes according to EN 1891 with a diameter from 11 to 14 mm.
Generally you can say:
- New body and/or thick rope: Cam/Clutch B
- Worn body and/or thin rope: Cam/Clutch A
