Load on Blocks<br />
WARNING<br />
The Working Load Limit (WLL) is the maximum resultant load which should ever<br />
be applied to a block and its fittings. Blocks used to fairlead (single sheave and<br />
snatch blocks) can be subjected to a load greater than the weight being lifted or<br />
pulled.<br />
