How is the connection made from stadia seat to stadia seat?
These are typically spaced across the front nose of the stadia unit above and pinned down into the upturn of the stadia unit below. A hidden connection can be achieved by casting a threaded insert into the bottom surface of the lower stadia unit. When erecting the stadia units, threaded rods are installed into the cast-in inserts in the upper stadia units and grout is poured into the sleeves in the lower stadia units. When the stadia units are set on each other, the connections are automatic and the connections lock as the grout in the void hardens.
