Sailboat rope clutch KJ50

The KJ50 is the original aluminum version of our 3-jaw heavy-duty ascender. A carbon version has been completing the range since 2020. 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. We have counted more than 60 KJ on the fleet of 33 sailing boats participating in the Vendée Globe 2020-2021. Convinced ? 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. – 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 Blocker 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.
