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(tm) / Teflon(tm) bearing for high load/low friction application.
