Karver KJ10 High Load Jammer Rope Ø 5-10mmThe KJ10 is the original aluminum version of our 3 jaw heavy duty jammer. The secret of KJ jammers 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. The jammer is no exception to the chore of cleaning but this has been thought about: The ascender is in 2 parts which makes it possible to extract the jammer

The KJ10 is the original aluminum version of our 3-jaw heavy-duty jammer. The secret of KJ jammers 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. 

The jammer is no exception to the chore of cleaning but this has been thought about: The ascender is in 2 parts which makes it possible to extract the jammer very quickly without having to disassemble its glued – screwed support. The result : an innovative and efficient jammer that does not let go and that does not damage the strings.

Rope Ø 6 -11mm

– Innovation : 3 jaws surround the rope (instead of 2 on all other jammers 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 be 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 jammer is installed as close as possible and limits the undesirable effects of the elasticity of the rope. It is very often found as a jammer on headsail tack.
– Performance : The rope does not slip. There is very little recoil when blocking.
– Convenient : the jammer 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 : The jammer can 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 rope 
– 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 laminate slipper

Did not disappoint!
Perfect Fit: Bolted right up to the engine block without any shimmying or modification needed. ​Strong Crank: The motor sounds powerful and turns the engine over significantly faster than my old, dying unit. Once hooked up, the car fired up instantly on the first turn of the key. No grinding, no clicking, just a smooth, high-torque start. Price: A lot more cheaper then your average auto parts stores. ​Build Quality: The solenoid connections are solid and the threads were clean. Packaging: The box arrived on time but a bit beat up, but the starter itself was well-protected in bubble wrap and undamaged.

Still working great!!
I really didn't have a good feeling about ordering a starter online, but I was in a situation where I didn't have the time to get to the auto shop before my day off and Amazon could get me this part just in time. So I reluctantly gave it a shot. When it showed up it had a couple of small black pieces of plastic loose in the box similar to the pieces shown in another review on here. It didn't look like they from anything functional. I really needed to get my wife's car running so decided to install it anyways. The install was easy and it was a perfect fit. The only draw back would be that the signal wire didn't click in place like the signal wire on the original starter. But it was a snug fit. It has been installed and working great for a month now. Very happy with my purchase. It also had a message from the seller when I opened the box giving the starter a 2 year warranty. Very cool. If the starters fails in the next two years I'll get on here and edit my review. So if your reading this then it is still working great.
