One pair of brand new rings. (One ring opened for inspection, the other still unopened.) These heavy duty rings (9mm thick, 28mm wide) will fit tube diameters of 110 - 150mm.
The rings are of typical Baader quality. They have five flats and mounting holes around the periphery, allowing two or more rings to be joined together for mounting two or more telescopes or finders in a number of configurations. The nylon tips on the ends of the stainless steel clamps rotate with respect to the clamps, preventing damage to the telescope finish.

$140 plus $18 shipping.
