Double Chainplates

Double Chainplates
Double Chainplates are designed for attachment of two (2) separate shrouds at the same location, usually an upper and a lower shroud. They are normally bolted to a bulkhead and pass directly through the deck. Double Chainplates are listed below by the size of the Pin they are attached to the rigging with. If you require Double Chainplates not listed here, we stock some others and are able to fabricate a variety of Custom ones, please forward a sketch with complete measurements and details for a quote.
