This adaptor is used to attach cameras, weights or guide tubes to 3" prism rails.
The lower part of the product image shows this application.
The sturdy clamp is designed for heavy loads. Clamping is not achieved by a simple screw pressing on the rail, but across the entire surface. The length of the clamp is 63 millimetres.
The clamp fits all large prism rails: Losmandy, Farpoint, Baader, Celestron ...
Using countersunk holes, you can attach any accessories, such as cameras, counterweights or guide scope rings, with 1/4" hexagon socket screws and M6 hexagon socket screws (screws are not included).
