The KJC50 is the carbon version of the legendary KJ 3-jaw high load ascender. Even though the aluminum version remains available, the KJC becomes the new standard. 

The secret of KJ blockers lies in 2 simple technical elements : a conical shape where the more you pull the more it gets stuck and the use of 3 jaws to distribute the load over 360 ° so as to never flatten or damage the ropes. Our blocker is no exception to the chore of cleaning but we have thought of you : The ascender is in 2 parts which makes it possible to extract the ascender very quickly without having to disassemble its glued – screwed support. The result : an innovative and efficient ascender that does not let go and that does not damage the strings. 

Rope Ø 8-14mm

– Innovation : 3 jaws surround the rope (instead of 2 on all other blockers on the market). The load is distributed on the rope and the sheath wears less.
– Innovation : The conical shape accentuates the hold of the rope. The more you pull, the more resistance there is.
– Design : The cone containing the locking mechanism can and installed without its foot in a reinforced “sock” installed in any location : deck, boom, mast, bowsprit,…
– Convenient : The KJ can be ordered with or without its stand
– Practical : The opening and closing (in the axis of the rope) can be controlled remotely by installing extensions. The ascender is installed as close as possible and limits the undesirable effects of the elasticity of the rope. It is very often found as a blocker on headsail tack.
– Ergonomics : The new KJC is now equipped with a jaw closure button on the upper part of the ascender.
– Performance : The rope does not slip. Very little recoil when blocking.
– Convenient : the ascender can be removed from the foot without tools. Maintenance and cleaning are easy. If necessary, the cone can be replaced very quickly.
– Performance : Extremely compact and light.
– Design : Online ordering allows the blocker to be installed in very small and even hidden locations.
– Performance : In the open position, the jaws open wide and offer very little resistance to the string
– Performance : The reduced wear of the sheath greatly limits string replacements. Investment in technical ropes is relevant
– Ergonomics : No constraint on the operations height (unlike a jammer that opens from the top : Each KJ can accommodate a wide range of diameters without affecting performance
– The KJ is also available without its foot (KJ CONE) in order to be installed in a laminated liner
– Aesthetics : KJ Carbon is also available with a thin layer of natural wood. It will thus fit perfectly into a teak deck.

Worth the buy

Helpful. I prefer this little guy over the gigantic book we were required to purchase along with this one. Barely opened the bigger one, only used this for my advanced assessment course and still got an A.
