ART Spiderjack 3 Product specifications are quoted from the retailer below: 【Specifications】 For DdRT only. ■ Weight: 511g ■ Suitable rope diameter: Clutch A: 11-12mm, Clutch B: 12-13mm, Clutch C: 13-14mm ■ Material: Aluminum + Stainless steel (frame) ■ Minimum breaking strength: 22kN ■ Safe working load: 200kg ■ Standard: EN 358 Clutch (Cam) A (Black: for 11-12mm) B (Red: for 12-14mm) C (Silver: 13-14mm) Cam B is installed as standard, but I was using a 12.7mm rope, so I used B as is. Cams A and C are unused. The hex wrench used for cam replacement is not included. You can purchase a 10-piece set at 100-yen shops, so please prepare one yourself if you don't have one. I purchased it about two and a half years ago and have used it on-site about 20-30 times. Of course, it can be used without any problems. *Please refrain from purchasing if you are looking for something like new, as it is used. I have used it with care, basically storing it in a case when work was interrupted, so I think the condition is relatively good, but please judge from the images. #TreeClimbing #Felling #Arborist #Forestry #SpecialFelling
