DB18 Dogbone (Stainless Steel), Tylaska Marine And Aerospace, Mfr#: DB18-SS

A dogbone is essentially a short structural rod that can be attached to the end of a line and used like a button or toggle to make a connection to another line, grommet or deck fitting. The tapered middle and symmetric ends make the part look like a bone, hence the name “dogbone.” The dogbone itself has been around since the days of the tall sailing ships and was originally made from a wooden peg. Over the years the device faded into obscurity but was recently revived due to better materials and a new appreciation of its versatility. The dogbone is a very convenient way for attaching the halyard line to the headboard as you can maximize sail height without the added length of a conventional shackle. It also works well for jib and spinsheets, outhauls, the connection of soft loops used for attaching blocks to deck fittings, and numerous other rigging applications. Unlike a knot, the dogbone connection does not jam up under tension and can be quickly attached or detached.
