Cone KJC25 without bracket for direct installation in a female cavity. The KJC cone can thus be perfectly integrated into a mast, a deck, a boom, a bowsprit, etc. with the aim of saving weight, bulk or seeking performance.
The KJC is the recent carbon version of our legendary KJ 3-jaw high load ascender. Even though the aluminum version remains available, the KJC becomes our 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. The result : an innovative and efficient ascender that does not let go and that does not damage the strings

Specifications

Strengths

– 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.
– Convenient : 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.
– 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

Tips

– We strongly advise against gluing the KJ cone in its housing. It is essential to be able to dismantle it to carry out maintenance operations.
– When designing the housing, consider incorporating a retention system to prevent the blocker from coming out when the voltage is taken.
– We note that the use of the cone alone allows to push the limits of the ascender by about 20 to 30%. This cannot be a contractual given since we are not in charge of the manufacture of the accommodation, but the results are there.
– We sell at cost price the molds which allow to create the female form of our ascender
– A KJ15 can hold 1.5 T but you must choose a rope capable of withstanding 3 or 4 times this load to prevent the sheath from breaking. This is a valid rule for all blockers in the market.
– The best results observed are with ropes whose sheath is composed of polyester and PBO
– No blocker on the market can block pure Dyneema. The KJ is no exception
– Like the majority of blockers on the market, KJs are not intended to be opened under load. You will probably be able to do this in an emergency, but it is not designed for that.
– It is possible to remove the locking system in the open position. The modification is done simply in a few minutes. In this case, it is customary to extend the main control with a string and use a cam cleat to keep the ascender open.
– Like all other blockers, the line must be well aligned on entry and exit. The tolerance is 5 ° at the entry and 10 ° at the exit.
– The KJs are blockers intended for both racing and cruising. If you have a problem with a slippery or damaged string, the KJ will easily fix it.
– The locking principle is identical between the aluminum version and the carbon version of the KJ. Beyond the change of material of the foot and the cone, the 3 main evolutions between the KJ and the KJC are the change from the main control of stainless steel cables to textile controls, the replacement of the closing zipper which is located under the main control for the KJs with a button located on the blocker for the KJCs and the replacement of the aluminum jaws in stainless steel jaws.
