B19 Powerblock Open Sideshell

The B19 MARCO Powerblock weighs only 148 lbs and packs a lot of power in a small package. The block is popular in many different seine fisheries and has been adapted for use in the diving and salvage industries for moving cables, welding leads, hoses, and other materials.

The open sideshell design is ideal for quick haulbacks for interrupted sets with a solid rubber coated sheave that offers good traction when hauling. This block is available with several options including the addition of a MARCO PowerGrip for improved hauling. The standard hydraulic drive motor is a high performance torque motor that requires only two hoses and uses no case drain.

For information on more information on MARCO powerblocks for diving, salvage or shore power cable handling please see our Utility Powerblock section.
