90mm Optical Tube security mounting ring set made in Japan
Unlike lower cost tube ring sets, these top quality rings are not hinged and their solid, one-piece construction is guaranteed to cradle your optical tube safely. Just slide it through the ring and adjust the tension.
Vixen Telescope Tube Mounting Rings are sold in pairs and have 1/4 - inch threaded holes at top and bottom. An optional Tube Ring Accessory plate can be fitted across the top of the rings for additional mounting options and greater stability when placed far apart.
