These restrainers keep the jib halyard (and other halyards such as the spinnaker or additional jib halyards) against the mast which provides a better angle to the halyard swivel, thus preventing the halyard from wrapping around the foil. The stainless steel brackets on the restrainer feature hardcoat-anodized aluminum sheaves that can accommodate both wire and rope.
