Our marine snatch block is a heavy-duty single sheave pulley block with openable side plates and swivel eye. The open side design allows fast wire rope installation without threading the rope end through the block. It changes cable direction and multiplies pulling force for heavy loads.
This cast steel snatch block is built for harsh marine saltwater environments. It is commonly used on ship decks, cargo handling, mooring, towing, offshore platform lifting, as well as land-based construction, mining and heavy rigging projects. The swivel eye rotates freely to keep a fair lead and prevent wire rope twisting during operation.
