The KJS12 is Karver’s first clutch designed for intermediate loads (600 kg to 2,000 kg working load). It was created to be installed on all cruising sailboats and is a serious competitor to all other clutches on the market. It complements the high-load clutch range (KJC). The design of the KJS makes it easy to stack multiple units together like a traditional bank.
The KJS12 won the prestigious Dame Award 2024 Innovation Prize in the Deck Hardware category.
Eco-designed: Made of stainless steel die casting to reduce raw material, waste, environmental impact, and extend product lifespan.
- A clutch with a traditional appearance yet many unique advantages at a competitive price.
- The entire mechanism can be removed without detaching the base, ensuring easy installation and maintenance.
- Captive mechanism during disassembly: no lost parts.
- Wedge design to increase holding power on the rope.
- Ultra-low-friction sliding pads: less wear and easier opening.
- Dual movable jaws: reduced rope wear and less friction when open.
- No top handle: Like our high-load KJC jammers, the KJS has no upper handle, allowing it to fit into tight spaces and be operated remotely. It also prevents handle breakage.
- Remote control: In just 5 minutes, you can disable the open-position lock and operate it remotely with a single rope.
- 70 mm mounting distance, identical to many competitors.
- High-performance jaws based on our high-load KJC technology to protect ropes, especially their covers.
- Stainless steel construction also minimizes bulk, making the KJS12 particularly compact.
- Lighter than many competitors despite its stainless steel structure.
