Show Solutions Spigot Truss Pin with R-clip

A spigot truss pin with its R-clip, the pin-and-clip pair that locks a spigot truss connection closed. The pin drives through the coupler and the R-clip springs into the groove so it cannot back out under vibration or during a lift. These are the small parts that disappear on a load-out, and a joint is not a joint without them, so most shops keep spares in the road box and in the rigging pouch rather than counting on the ones that came with the truss.
