Choose from our standard Wire Blocks with narrow heads and sheaves or our Eye-Jaw Wire blocks. Either are perfect for use with Control Lines or Halyards. Stainless cheeks offer high abrasion and chafe resistance as well as opening to accept swaged or nicro pressed wires. Eye Jaw Wire Blocks are easy to use with Runners, Backstays or any area requiring strong wire support. They also use our Nomex/Teflon Bearing for high load/ low friction application.
