Pair of cast-metal rings of 105mm inner diameter that attach to a mounting plate for Orion guidescopes of up to 80mm aperture. Each ring has three black nylon alignment screws, which will not scratch guidescope finish. Rings attach to mounting plate with two 1/4"-20 hex-head cap screws (included). A small wrench is also included.
Onze deskundige opmerking:
De tubusringen zijn ideaal voor 80 mm-refractors. Ze zijn te groot voor de meeste 70 mm-refractors. De 3 bevestigingsbouten zijn van kunststof en kunnen dus geen krassen op de tubus maken.

These tube ring clamps are ideal for 80mm refractors, but are too large for most 70mm refractors. The 3 retaining screws are plastic to avoid any scratching with the finder scope.
