Feature - Wire blocks have purpose designed narrow sheaves and grooves.
Applications - Exit and sheave boxes are ideal for applications where lines (rope or wire) need to be led through decks, bulkheads or spars minimising friction and chafing. - Wire blocks suit halyards, vang and backstay applications. - Exit blocks minimise friction in lines passing through the deck or exiting masts and booms. Available in single or twin sheave versions. - Stainless steel cheek, clevis pin head blocks are ideal for spinnaker halyards where speed and minimum friction are important.
Construction - U.V. stabilised Acetal sheaves. - Nylatron sheaves (wire blocks and sheave boxes). - Grade 316 stainless steel cheeks.
