Maximum Working Load: 136 kg
Breaking Load: 454 kg
Shackle Ø: 4 mm

The Carbo 40 mm Ratchet Block to be mounted stands out with its compact and lightweight design (only 52 g), combined with impressive robustness featuring a breaking load of 454 kg. Thanks to its optimal ratio between sheave diameter and load capacity, it surpasses many traditional blocks, facilitating maneuvers even in demanding sailing conditions. The disengageable option on certain models (2608, 2609, and 2614) offers additional flexibility, ideal for crews looking for versatility and efficiency.

Carbo Ratchet Technology: ensures precise rope control, while reducing fatigue during long manual adjustments.
High-performance material construction: contributes to exceptional durability in the most extreme marine environments.
Controlled release: facilitates rope management during sail changes or rapid tacks.
Easy installation: thanks to its small footprint and light weight, this block integrates easily into all types of modern rigging.

Our tips for choosing

Workload and breaking load

Choose your pulley based on the workload it will have to handle and the desired gear ratio. The orders of magnitude vary depending on the support: 400 to 500kg for the mainsheet or cunningham of an 18-foot catamaran, 100 to 200kg for the mainsheet or downhaul of a 420 dinghy for example.

Coefficient of friction

Modern ball bearing pulleys offer a much lower coefficient of friction than those without balls and are recommended for maneuvers that require constant adjustment (mainsail sheet, downhaul, cunningham, spinnaker essentially).

Restraining force

For the mainsheet which is not always fully tightened, or even never on some boats which require constant adjustment (29er, 49er, Class A,...) as for the spinnaker sheet, favor automatic or non-automatic winch pulleys, which considerably save muscles and gloves thanks to a retention that can go up to 70% of the workload.

Sheave diameter

Choose the diameter of the pulley according to the diameter of the rope it will guide. For example, depending on the support and workload, a 40 or 57 sheave is very suitable for a 6 to 10mm mainsail sheet. For Cunningham or downhaul type maneuvers, 16 or 22 sheaves are suitable.

Material

Stainless steel, carbon, composite, it's essentially a matter of weight, with an impact on the price: it all depends on the importance you attach to it. If the pulley is to guide a cable, use aluminum sheaves which will be much more resistant than composite materials.
