Includes: Plate, cradle and locking clamps.
The Cradle is a precision machined unit that goes exactly one half the way around the actual body tube of the SCT. It is lined with a layer of hard felt to prevent any scratching of the paint. The scope is held into this cradle with stainless steel hose clamp style straps. This allows a dove tail mounting system to still be used on the top to hold anything one is inclined to mount up there. Holes have been tapped on the sides of the Cradle arms to allow mounting accessories lower down to minimize excess weight farther from the rotational center line of the mount, increasing rigidity drastically.
