A two-way corner block for 12-inch box truss, the fitting that joins two truss runs at a right-angle corner. Two-way is the simplest block in the range and the one most rigs need the most of: it builds the four corners of a rectangular grid, the top of a goalpost, or the turn where a downstage run meets a side run. Using blocks rather than mitred truss means the grid comes apart into standard sticks that pack flat and get rebuilt in a different shape next week.
