4190 Snatch Block & Shackle
The US Cargo Control 4190 snatch block pairs an 8-inch sheave with a 3/4-inch wire groove and an integrated shackle. It redirects a winch line or doubles pulling capacity for recovery and rigging tasks. The assembly suits off-road recovery, marine deck work and industrial pulling where a single block is required.
California Proposition 65 notice
This product carries a California Proposition 65 warning because it contains a chemical known to the state to cause cancer. The notice applies to the item as supplied and does not describe a thermal, acoustic or electrical characteristic. No power draw or operating noise is generated by the block itself.
Sustained load behaviour
Under continuous tension the sheave rotates on its bearing to maintain line alignment and reduce friction heating. The steel construction resists deformation when the rated line load is held for extended periods. The block is not suited for applications requiring powered operation or active cooling.

Questions about this item
How do I install the 4190 snatch block with a 3/4" wire rope, and what step is often missed?
Open the side plate, seat the rope in the 8" sheave groove, close and latch the plate securely, then attach the shackle to a rated anchor point — forgetting to fully latch the side plate is the common error.
What maintenance or replacement will the 4190 snatch block need over time?
Inspect the sheave groove for wire-rope wear, check the shackle pin and threads for deformation, and lubricate the sheave bearing periodically; replace the block if the groove deepens or the shackle shows cracks.
What limit appears first on the 4190 snatch block during sustained heavy pulling?
The 8" sheave diameter sets the minimum bend radius for 3/4" wire rope, so prolonged loading at sharp angles accelerates rope fatigue and groove wear before the block structure yields.
