US Cargo Control 4180 Snatch Block
The US Cargo Control 4180 is a snatch block fitted with a hook for lifting and pulling tasks. It accepts 1/2" wire rope and runs on a 4.5" sheave. Riggers and recovery operators use it to change line direction or increase mechanical advantage.
Practical limits of 1/2" wire and 4.5" sheave
A 4.5" sheave diameter sets a minimum bend radius for 1/2" wire rope; tighter bends accelerate fatigue and reduce rope life. The block is designed for in-line loads within the working-load limit of the wire and hardware used. California Proposition 65 warns that the product contains a chemical known to cause cancer.
4.5" sheave diameter decides fit
The 4.5" sheave diameter is the single specification that determines whether this block matches your wire rope and block-and-tackle layout. If your system requires a different sheave size or wire diameter, this unit will not integrate correctly.

Questions about this item
Which size of the 4180 snatch block should I choose for my 1/2" wire rope?
The 4180H4.5 model has a 4.5" sheave diameter and is built for 1/2" wire rope, so it matches that rope size directly.
What does the 4.5" sheave diameter mean when the block is under load?
A 4.5" sheave gives a gentler bend radius for 1/2" rope, reducing wire fatigue and wear during lifting or pulling operations.
How does the hook attachment affect the way I rig this snatch block?
The hook lets you connect quickly to a sling, shackle or anchor point, making the block easy to reposition without tools.
