Snatch Block for 3/4" Wire Rope
This snatch block with shackle is built for lifting and pulling tasks that use three-quarter inch wire rope. The six-inch sheave diameter suits the specified rope size and allows the block to redirect the line or create mechanical advantage in a rigging system. It is intended for professional riggers, recovery operators and industrial maintenance crews who need a reliable redirect point.
Verify Rope Diameter and Sheave Fit
Before ordering confirm that the wire rope on site measures exactly three-quarter inch so it seats correctly in the six-inch sheave groove. Check that the shackle pin and bail dimensions match the anchor points or hooks you plan to use. Ensure the working load limit of the block meets the forces in your specific rigging plan.
Behaviour Under Sustained Load
Under continuous tension the sheave rotates on its bearing to reduce friction and heat buildup on the rope. The steel construction resists deformation when the block is held at full working load for extended periods. The shackle remains secure through repeated load cycles without loosening when the pin is properly tightened.

Questions about this item
Does the 4190S6 snatch block arrive with the shackle already attached or do I need to buy it separately?
The 4190S6 snatch block includes the shackle as part of the unit so nothing extra is required for basic rigging.
The listing shows only the 3/4" wire by 6" sheave version; is there another capacity I should consider?
This specific model is built for 3/4" wire rope and a 6" sheave diameter; no other size or capacity is offered under this part number.
How does the 6" sheave diameter affect the bend radius when the block is under load?
A 6" sheave gives a bend radius that matches the recommended minimum for 3/4" wire rope, reducing fatigue on the strands during pulls.
