Callipers
Two curved lifting irons which connect a STONE CRANE to the RUNNER STONE via pins inserted into sockets set into the edge of the stone. The curvature of the irons allows the stone to be turned over while being suspended. Compare a STIRRUP which serves the same function but is a single piece of metal.
