Double Swivel Block w/ Hook SS304
"Double swivel" refers to the connections, not the sheave count: this is a single-sheave block with a swivel hook on one end and a swivel eye on the other, so both ends rotate independently to help keep wire rope aligned as the load shifts. That makes it a good fit for rigging setups where the load or pull angle changes during the lift rather than staying fixed. The 304 stainless steel body resists corrosion in wet and outdoor environments, and the brass-bushed sheave keeps rotation smooth under load.
Common Uses
- Rigging and load positioning where the pull angle shifts during the lift
- Marine and outdoor applications needing corrosion-resistant hardware
- Small-scale hoisting in confined rigging spaces
- Setups where a fixed-orientation hook would bind or twist the wire rope

This block meets or exceeds ASME B30.26 requirements with a 4:1 safety factor built into the assembly break strength. That rating covers the hardware's design, not your specific rigging setup - confirm your full rigging chain (wire rope, hook, connection points) is matched to your lowest-rated component, and follow applicable OSHA rigging standards and your equipment documentation for setup and inspection requirements.

Frequently Asked Questions
Is this a double-sheave block?
No. "Double swivel" refers to the two rotating connection points, a swivel hook and a swivel eye, not the number of sheaves. This is a single-sheave block.
Why does it have a swivel at both ends?
Independent rotation at each end helps keep the wire rope aligned as the load or pull angle shifts, reducing twist and binding compared to a fixed hook.
Why 304 stainless steel and a brass bushing?
304 stainless resists corrosion in wet, salt-exposed, and outdoor conditions, which matters for marine use and equipment stored outdoors. The brass bushing supports smooth sheave rotation and reduces wear on the wire rope.
What size wire rope does it fit?
This block is sized for 1/2" wire rope with a 3" sheave and a 1,450 lb working load limit.
How do I know if the working load limit is enough for my application?
Identify the maximum load your rigging setup will actually pull or support, then confirm this block's 1,450 lb WLL provides margin above that figure. If your application needs higher capacity, size up to one of our other snatch block collections.
