LIGHT ENOUGH TO ALIGN TO THE LOAD
Harken Oceanic Cable blocks are used on vessels to safely lead cables & towed objects overboard. At only 19.3 kg (42.5 lb) the 500 mm (19.7 in) sheave diameter pulley is light enough to align to the load, optimizing cable tracking.
Simple to use
The Oceanic Cable block has been used by Woods Hole Oceanographic Institute, University of Rhode Island, and the University of Delaware Oceanographic Research departments as well as many other ocean research organizations.
Maintaining the block is easy
Simply flushing the block through with fresh water after use will keep the self-lubricating bearings free rolling. If further maintenance is required, only one hex wrench is needed to disassemble the Oceanic Cable block. All the bearings are captive, so there is no need to worry about losing parts.
