These are 7" rings that I received with my purchase of an older Astro-Physics 6" OTA. Hardwood construction, felt lined, 7 inch ID, plate length is 15 inches. They safely carried the A-P OTA for years, but I needed to piggy-back another OTA and went to a new set to handle the additional stress.
Yours, shipped within the CONUS for $60. Payment by check or MO, please.
