The Schaefer 300-05 Marine Block Single Ball Bearing Swivel Shackle is a high-performance component designed for use in marine applications. This shackle is engineered to provide superior strength, durability, and ease of use for boaters and sailors.

The heart of this shackle is a marine-grade, 316L stainless steel construction.

The shackle also includes a marine-grade, self-aligning block. This block is designed to keep the shackle properly aligned, even under heavy loads, ensuring that the shackle remains securely connected to the boat and the line. The block is also self-draining, which helps to prevent water buildup and potential damage to the shackle.

The Schaefer 300-05 Marine Block Single Ball Bearing Swivel Shackle is designed for use with lines up to 3/4 inch in diameter. It is rated for working loads up to 10,000 pounds, making it a versatile and reliable option for a wide range of marine applications.

In summary, the Schaefer 300-05 Marine Block Single Ball Bearing Swivel Shackle is a top-quality, marine-grade component that offers superior strength, durability, and ease of use. Its single ball bearing swivel design provides 360-degree rotation, while its marine-grade, self-aligning block ensures proper alignment and secure connection. With a working load capacity of 10,000 pounds and CE certification, this shackle is an essential addition to any marine application.
