Strong, lightweight, and low friction, these versatile blocks are the workhorses of the Harken® line. Their caged roller bearing design reduces friction by keeping each bearing isolated and allowing dirt to fall between the bearings making for a freer running pulley. They are also fully serviceable, with few component parts and no loose balls or rollers to misplace. Unlike blocks that are riveted together, three Allen head fasteners allow quick disassembly for service.
All Harken pulleys can be proof tested and marked with safe working loads and serial numbers on request.
