This 12" plate fills the void for those customers whose telescopes use the Vixen-style mounting plate. Now there is no need to replace your existing Vixen-style bar, rings, or clamshell to accommodate your Astro-Physics mount.
The top portion is a female plate that accepts Vixen-style bars. In order to retain the tilt-in feature of the dovetail, the sliding bars must have an approximate width between 1.65" (4.2 cm) and 1.8" (4.5 cm) and that have a 75 degree bevel.
The bottom dovetail of the plate has the ubiquitous D-style male dovetail, allowing it to be clamped into any saddle plate which accepts this size plate.
The saddle portion of this plate has a hole in the center to relocate one of the knobs for use with a shorter sliding bar. With a knob in the center and in one of the outer holes, you can use a plate as short as 4.5" (11.4 cm) and still maintain two clamps engaged on your sliding bar.
This plate ships with one 1/4 - 20 x 1/4" socket head screw to use in the bottom of the SBD2V plate as a safety screw for this plate. Please install it in the appropriate end to function as a safety stop. The screw packet also includes a 1/4 - 20 x 1/4" low-profile socket head cap screw for use as a safety stop in the bottom of your Vixen-style, male sliding bar.
