What is a Block?

 Snatch Block

These are single metal, internal bound or SRBF blocks, in which part of the shell is hinged to form a `gate’ which allows a bight of a rope to be inserted into the swallow from one side. They should not be used when a solid block is available for the job and they should NEVER be used when the safety of life depends on them because the gate may open if a sideways pull is exerted. Ideally these blocks should be used for lead blocks during rigging evolutions.The maintenance required depends on the type of block, additionally the gate will require a light greasing or oiling. Avoid applying too much grease to pin springs as this generally attracts dirt and more frequent checks and maintenance may be required.
