The Pin and Cotter is a locking pin set used in Alupan panel formwork systems for the fast and secure fastening of props, connection plates, and various steel elements. The pin passes through the connection holes of the elements to enable assembly, while the cotter acts as a safety lock by preventing the pin from falling out and the connection from opening. This prevents connections from loosening under vibration and load changes during concrete pouring. This solution, which requires no separate nut, saves time on site and offers practical use. Thanks to its durable steel structure, it is suitable for long-term use and can be repeatedly removed and reinstalled. The Pin and Cotter provides a safe and economical connection solution especially at points where props, work brackets, crane hooks, and other auxiliary equipment are connected to the formwork system.
