Karver KJ50 High Load Jammer Rope Ø 12 - 22mm

Karver KJ50 High Load Jammer Rope Ø 12 - 22mmThe KJ25 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 KJ25 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
