A special prism with a special clamp is an ideal product for rail surveying. A standard prism cannot be turned to any direction so it can be used only for some measurements. The clamp is equipped with circular level vials. The prism (standard version) can rotate around its vertical axis or the prism (rotating version) may be tilted. It is mounted with a clamp. It is made of aluminium, and its frame is made of anti-corrosive material.
