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.

It's lasted
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
I've had this bed for 5 years and it is still in great shape. Washes up in the washing machine just fine. My littlest dog absolutely loves it and is lost when our other bigger dog steals it. She barely fits in it but she loves it too. Ha! Good quality at a good price. Couldn't ask for more.

My Puppy Loves It.
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
I didn't know what to expect when I saw this advertised, but some reviews said that their puppy had chewed on it and it was still holding up with no holes. So, I decided to get it and see for myself. I have to say that my puppy loves it and chews on it and it is holding up very well. No holes yet and I suspect after all her chewing and no holes, there won't be any. Nice size for a 25 pound dog and smaller. Well built and nice looking bed. It has enough padding to make it soft for my puppy. I got it big enough, so she can grow into it, too. Well satisfied and I do recommend it.

Great basic dog bed
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
We really needed additional places for my dog to rest, besides hanging out on the furniture. He gets to be a little jerky and presumptuous, thinking he owns the joint when he lies all over the bed and couches. So the extra dog beds were necessary additions to the house. He took to this one right away. Sure, he still will try to sneak onto the human bed, the couch, the chair - especially when food is involved in the picture. But he does like this bed. The only real negative I have is that it's whitish on top. It shows dirt kind of easily and time will tell how well it will stand to multiple washings. It's soft. It's cushy. It looks pretty descent for a dog bed. He can curl up in it nicely and relax. Basically it does what it should and he seems relatively happy to hang out on it. Now, if Amazon could make a dog bed that could actually train the dog - that would be incredible!

Better than beds I've spent double the money on!
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
This bed is actually amazing for the price. My chihuahua digs a hole through every bed he's ever had except this one. The bottom actually went flat before he was able to dig a hole into the fabric. But since its such a great bed, i cut open the bottom and restuffed it from the filling from an old pillow and stitched it back up so he can keep enjoying it. Abd if he eventually does dig a hole in it, ill be rebuying this same bed.

My cat used it right away!
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
My large long-hair orange cat is a bed hoarder. He has at least 5 or 6 beds around the house, and uses every one of them (at different times, of course). But lately he's started sleeping on my pillow during the day, but going to bed at night on a pillow covered in his long orange hair wasn't cutting it for me. So I purchased one more bed for him - because heaven help me if I should move one of his other beds. What we won't do for our babies! Anyway, I put this new bed near my pillow and he's been using the bed instead of my pillow. It's soft and the bolsters are thick and it's just the right size for him to curl up in! He loves it! Win-win!
