US Cargo Control 4190S6 Snatch Block w/ Shackle 3/4" wire 6" sheave

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.
