The KJC10 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 5-10mm

– 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.

Clark's Wallabee's are the best shoes ever made!
I was looking for a new pair of shoes, after one of my Clarks casual shoes (made in india) literally split in half. It only had 8 months of use! I was so angry, so much so that as a loyal Clark's customer I vowed to move on to another brand of shoe. So I began my search, and search, and search... I just couldn't find any pair of shoe that exited me as much as Clark's did. I began to reminisce on my first pair of Clark's that started it all. The Wallabees. The quality in craftsmanship, the nice thick leather, the stitching, and the indestructible weird looking jelly soles. These things could take a hit. I mean I wore them consistently for two years and they just wouldn't budge. I eventually needed something different, so I put them in the closet; only to come out when ever a pair of shoe wore out and I needed a something while I made another purchase. After about 2 years of that I realize I shouldn't be buying more shoes I should be wearing my wallabees. So I wore them for several more years until I finally decided its was time to part... What a mistake. Here I had a pair a shoes that lasted me almost a decade I parted away for no real good reason. It took me many more years of wearing other Clark's and other brands to come to this realization. The Wallabee's are the best shoes ever made! I broke my vow of not buying Clark's after that indian made piece of crap, and decided to buy these. To my surprise the wallabee's are no longer made in England or Ireland, but instead made in China! I was sceptical as to how great the quality may be. I mean I lost faith in Clark's after all. But after careful inspection, these shoe's look, smell, and feel just like the originals. The craftsmanship looks the same as well (a little more modern support). I did some research and turns out China has one of Clark's best shoe factory in the world. I can not judge these shoes by where is was made, but how they fare out with the old ones. So far I'm very very happy! I will wear these and put it to the test of time, and see if they will go for almost a decade as my originals did. At this point they once again take their place as my number one favorite pair of shoes.

Love them!
Size: 7, Color: Maple Suede
These are a classic! Amazing materials and product. If you have never owned a pair, be aware that the soles will get dirty quickly and visibly noticeable. I would say true to size in what you were in sneakers.
