Deck Mount Chainplates

Deck Mount Chainplates
These Chainplates are designed to be bolted directly to a flat Deck. Generally used for Shroud attachment on smaller boats, but sometimes used in Forestay and Backstay applications, they are suitable for larger boats and in other applications where the Deck is sufficiently reinforced. Deck Mount Chainplates are listed below by the size of the Pin(s) they are attached to the rigging with. If you require Deck Mounted 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.
