Parallax Standard Rings for 4" OD Tubes

Parallax Instruments Standard Rings for 4" OD Tubes

These 95mm outside diameter split tube rings are specifically designed for the Tele Vue Genesis, Genesis SDF, TV-101, TV102, and NP101, and the Orion ED80. They 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.

Parallax Instruments Product Number: 4IN

When you get to your shopping cart, please write what you are going to mount the rings to in the comments section. Most standard rings are in stock, however, certain mounting set-ups may require some custom drilling and thus shipping may take a little longer. Please call us at 1 (800) 483-6287 or email us with any questions. Thanks!

Size does not work

Wife bought a set for these for me. Nice and solid, but they DO NOT fit the Orion 80ED (despite the claim that they do) , unless you don't mind the tube sliding freely.

Great Quality

I bought this for my TeleVue 101 IS and they work great. Sturdy, excellent finish and well made. Perfect fit with the ADM universal plate.
