A Type Swivel Shackle
B Type Swivel Shackle

Swivel shackles provide a 360 degree rotation for various alignments between two chains or objects needing to be linked, and are used in conjunction with blocks and rigging to provide articulation or rotation.

Technique Characteristics of the A Type Swivel Shackle
1. The surface of the ship fitting has no defects, such as cracks or inner layers.
2. The tolerance of our swivel shackle is ±2.5%.
3. Other technical performances are in conformity with LR rules.
4. The material used to make the swivel spring shackle must be the same grade material as that of the chain cable.
