This auction is for a pair (2) of Ruland Manufacturing Rigid One Piece Shaft Coupling Clamps. The P/N is CLC-12-12-F, Bore A is 3/4", Bore B is 3/4", and there are TWO in the original box. They have been on the shelf for a long time, so the box is showing its age, but the clamps are still contained in their original plastic protectors. So, they're still new, but may have some flash rust on the surface. They will be shipped to you in the USA for free! Let me know if you have any questions and thanks for looking. Location - 9F
