Falconn truss
The FALCONN connection itself is based on a simple locking system that does not require usage of hammers and safety pins. There are two safety rings at each connection. First one locks the connector in position and the second one secures the connection. This double locking system ensures proper strength and safety of the connection part.
FN24 loading tables are identical to the standard spigoted truss (FT24)
