"Harken's Midrange blocks' robust construction makes them ideal to handle the high loads found in mainsheet, halyard, spinnaker sheet and control line systems on medium and large offshore boats. The wide-diameter 3 in (76mm) ball bearing sheave accepts 9/16 in (14 mm) line. These high-load Midrange blocks use Torlon ball bearings."^^<http://www.w3.org/2001/XMLSchema#string>
