Vixen Tube Rings (pair) I.D. 155mm

Tube rings and accessory mount rings clamp onto telescope tubes to provide mounting points for accessories and mount heads. Ring models are designated by their inside diameter. Both types can be joined by dovetail tube plates on the bottom for attachment to Porta, GP-Series and SPHINX (SX) mounts.

Tube Rings are sold in pairs and have 1/4"-20 threaded holes on top and bottom. There are two styles of Vixen tube rings: a "hinge-style" and "slip-on" style. An optional tube ring accessory plate can be fitted across the top of the rings for additional mounting options and greater stability.
