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.

Tooth whitener
Flavor Name: A Coconut+Green Tea+Peach
I have used the green bottle so far! As soon as you bite into one, it starts to foam up. I let it foam for a few minutes, and then I brush my teeth. It does freshen your breath and I think it's making my teeth whiter! I have not had a chance to try the other flavors yet. The flavor is mild but good! It is fun to use!

Flavor Name: A Coconut+Green Tea+Peach
These are very interesting. They work very fast like they said. The taste isnt bad so far ive tried the peach and its nice and strong. Only thing id say is its not like brushing your teeth like it claims its more of like a stronger breath mint that foams. Other than that id say its a great mint and product as a mint that you need to spit out haha. I look forward to using them.

Don’t waste your money.
These are horrible tasting …not even able to keep it in my mouth. Four people, including myself, tried them and everyone spit it out immediately. Don’t waste your money.

Wow. Explosion of froth and mouthwash in one little tablet.
Flavor Name: 2-Bottle Green Tea
I love these for travel, and put some in a tiny container in my purse, too. You just have to spit it out - no rinse necessary. I might try a different flavor than the green tea. Don't love it, but do love the product.
