PLEASE - do not use WD40 or CRC lubricants on your blocks. These damage the surface of the balls. Rinse in fresh water to get rid of salt build upSpecifications: these recommendations are for normal use. If you plan to use these blocks in exceptionally high load areas, we recommend switching to the next higher series of blocks.
If you are using a single block as a turning block and the line is coming back at around 180 degrees, the safe working load is HALVED. You are advised to use a foot block or high load block.
