Common Concerns Answered
Is a plain bearing block sufficient for my high-performance sailing needs?
While ball bearing blocks offer marginal gains in very high-load, low-friction scenarios, this Barton Marine block's plain bearing system with its precision acetal sheave and large brass bearing provides excellent free-running performance for most general-purpose rigging and control lines. Its robust design and substantial working load capacity make it a reliable choice for a wide range of applications.
Will this block withstand heavy and prolonged use?
The acetal sheave on this block is designed for durability. While any plain bearing block can show wear over extended periods of extremely heavy use, this model is engineered to meet demanding sailing conditions and offers a strong value proposition for its intended applications. For extremely heavy-duty, continuous use, alternative block types might be considered, but this block is built for robust general-purpose service.

The Barton Marine Size 2 Single Upright Block features a Safe Working Load of 370kg (815lbs) and a Breaking Load of 740kg (1630lbs). It is crucial to assess your specific rigging load requirements to ensure compatibility. This rating is robust for typical control line applications on many sailboat sizes.
