With the quick coupling, you can attach your telescope or camera safely. The clamp is especially suited for building double connections where a high load capacity is needed. Through the areal clamping and two clamping screws, a high clamping power can be achieved, while your accessories are protected against unaesthetic pressure marks. A safe and precise clamping of your telescope: Whether you want to clamp a telescope from Vixen, Skywatcher, Orion..., you simply attach a GP level dovetail bar to the telescope. With most telescopes, this bar is already included. The bar is simply clamped with the pressure screws and fixed. You can also shift the telescope in the clamp for achieving an even better equilibrium. Additionally, the length of the dovetail clamp prevents vibrations. The wall thickness is constructe for highest loads. At the thinnest point, the clamp is 15 mm thick! The clamp itself can be adapted to a mount, to the counterweight shaft or another dovetail bar, building a double connection. Extremly flexible through 9 countersunk bores: For attaching the clamp, 9 bores are available for M6 and 1/4" screws. All functions, especially the clamping, are completely kept. The clamping screw can be used without problems. Technical Details: Suitable for: GP level dovetail bars. Dimensions: 87 mm x 87 mm (116 mm with screw). Load capacity: approx. 20 kg. M6 Bores: Four M6 bores at 38 mm distance square, two M6 bores lengthwise. One M6 bore in the middle with two drilled (but not threaded) to accommodate screws up to 6mm in diameter, center-to-center screw hole spacing is from 35 to 63mm.
