Snatch Block H420 & H421
Snatch Block H420 & H421 is for hoisting, lifting, pulling, or dragging.
It is often use on truck cranes and winches, and in the logging, mining, and construction industries.
Snatch Block connects to Lifting Slings, Chain, Hooks, Shackles, and other Rigging Hardware.
A single line sheave can be used to change the direction of the pull to a favorable direction, while increasing the load on the block significantly compared to the lead line.
When suspended, the theoretical mechanical advantage increases to equal the number of lines going to the Snatch Tailboard Block.
