This ratchet block, manufactured by Ronstan, a renowned name in the marine industry, is specifically engineered to deliver reliable and durable performance under heavy load and extreme conditions.

The primary feature of this ratchet block is its 40 ball bearings, which ensure minimal friction and maximum load capacity. Each ball bearing is meticulously placed within the housing to facilitate seamless rotation and reduce wear and tear on the block.

The outer shell of the block is made from high-quality, marine-grade polymer. This material offers excellent resistance to UV radiation, saltwater, and other harsh environmental elements, ensuring the longevity of the block. The polymer shell is also lightweight, contributing to the overall weight reduction of your sailboat.

The Ronstan 8093-12 RF46151 40 Ball Bearing Orbit Block Ratchet is designed with a compact and ergonomic shape, making it easy to install and use. It can be mounted on various surfaces, including the cockpit coaming or bulkhead, using the appropriate mounting hardware (sold separately).

In summary, the Ronstan 8093-12 RF46151 40 Ball Bearing Orbit Block Ratchet is a reliable and efficient sailing accessory that is perfect for those looking to simplify their sailing experience. Its high-capacity ball bearings, self-gating mechanism, marine-grade polymer construction, and compact design make it an essential addition to any sailboat.
