D-ring
Encyclopedia : D : DR : DRI : D-ring
A D-ring is an item of hardware, usually a metal ring shaped like the letter D. It may be used at the end of a leather or fabric strap, or may be secured to a surface with a metal or fabric strap. For light loading applications such as clothing and luggage, D-rings made of plastics such as nylon may be used, as they weigh less and are impervious to rusting.
A common application for a D-ring is at the end of a tow-rope or chain, to allow one to create a bow around an item or part of an item that is being towed by a vehicle. They are commonly used with a chain to tether a boat to a dock or tree when it is being moored.
