It consists of two Vixen-style dovetail bars that are bolted together so that one side fits into the dovetail slot in the head of a Vixen, Celestron, or Meade equatorial mount or into one side of a VSBS, while the other side accepts Losmandy Vixen-style accessories such as the #VA dovetail accessory adapter. It weighs 2.35 lbs., is 12.25” in length, is 1.25" thick, and comes with two safety lock knobs that thread into holes in the dovetails to keep the dovetail from sliding out of the mount should the dovetail lock knob accidentally loosen during use.
