DetailsThese 3" outside diameter split tube rings, specifically designed for the Tele Vue TV-85 Refractor, are made of die-cast aluminum, finished in gloss black paint, and lined with felt. The hinges, no-tool knobs, and hardware are made of stainless steel for long life and easy telescope installation and removal.
The rings are installed onto your mount or mount dovetail plate via a 1/4"-20 thread mounting hole that is drilled and tapped in the flat boss on the bottom of each ring. A similar hole is drilled and tapped on the top boss so that accessories, such as a piggyback camera mount, can be attached.

Product QuestionsDoes the tube dimension consider the felt? I have a TV-76 and purchased rings some time ago that are exactly the 3" OD of the scope, except the felt liner effectively lessens that to where the rings do not fit.Question by: Frank Spasaro on Feb 12, 2017 7:39:00 PMThe rings are just a hair larger than 3" and the felt is designed to make the ID just a hair smaller, so that the felt is compressed somewhat when the rings are tightened. This compression prevents the rings from slipping when properly attached.Answer by: Chris Hendren (Admin) on Feb 16, 2017 8:32:00 AM
