This bronze oar clamp makes it possible to lock your oars securely into your boat when you aren't using it. The arms of the clamp fit over the shafts of your oars while the body of the clamp passes through a hole drilled in the thwart of your boat. A padlock (not included) can then be locked through one of the holes in the base of the clamp to prevent its removal.
An optional socket is available separately to fit the hole in your thwart for a neat finish.
The clamp and socket are made of polished silicon bronze. The maximum oar loom diameter the clamp will fit is 54 mm.
