These TMB 114mm split and hinged optical tube mounting rings are made of solid aluminum, anodized black for long life. They are felt-lined and have a large hand-tighten knob to lock them on your optical tube. A heavy nylon washer prevents the knob from marring the anodized finish. The rings have a 114mm (4.5”) internal diameter specifically to fit the TMB-92 refractor, but will also work with any other refractor having a 114mm OD tube. The rings weigh 25 oz. each.

There are five 1/4”-20 thread mounting holes on bottom of the rings for mounting on most equatorial mount dovetail plates. One hole is centered in the flat mounting boss in the bottom of each ring. It is flanked by a pair of holes on 60mm centers, and a second wider pair of holes on 80mm centers. An identical set of five holes on the top of each ring allow installing a second dovetail plate to carry accessories.

This pair of precision machined aluminum guide scope rings have a 125mm inner diameter (ID) and are compatible with guide scopes up to 100mm in aperture. The deluxe machined guide scope rings are lightweight at just 4.8 ounces each, yet they're strong enough to not flex during use. Each ring has three knurled aluminum alignment screws positioned equidistantly which allow you to position a guide scope precisely and securely.
