Product Details

WARNING: Telescope tube rings have to be sized very carefully and perfectly. They only work within an extremely narrow range up to the ring's specified inside diameter. DO NOT PURCHASE rings if your tube is even 1 or 2mm larger than the ring size. They will NOT fit! Measure your own telescope tube very carefully BEFORE purchasing these. Please also do not go off what others may have stated elsewhere online or in our reviews. Manufacturers are known to change specifications between different production runs. Finally, we do not have tube sizes or compatibility information so we will not be able to recommend rings or confirm your choice.

Rings will fit tubes with an outer diameter of 3.47" - 3.54" (Approx. 88 - 90mm).

These tube rings are high quality, cast-aluminum mounting rings that can be used for mounting telescope tubes on various mounts or on guidescope rails. All rings are hinged, felt-lined and have clamp-style rings for easy mounting or repositioning of the optical tube. Most rings have clamping knobs while a couple of size have clamping clips instead. Please see the photo for this product to determine whether it has a clamping knob or clip.

The base of the rings has a metric 6mm mounting thread. Gunmetal dark gray finish. If the outer diameter (OD) of the telescope is a little smaller than the inner diameter (ID) of the rings, you can shim the inside of rings with extra felt (not included). Price shown is for a set of 2 rings.
