Head House w/Silos 9-1/2 x 5 x 11" 24.1 x 12.7 x 27.9cm A Prairie Skyscraper for Your Rural Scenes.The most identifiable structure in many grain-handling complexes is what most people call the elevator. Tall in stature, the cylindrical silos are landmarks along the railroad tracks. On top, the head house contains the conveyor leg and piping to each silo. The Head House w/Silos kit includes eight silos, a top head house structure, a truck dock with loading doors and rooftop vent details. It's a great addition to any grain complex and is ideal for use with the Conveyor Leg kit (933-2936, sold separately) for loading covered hoppers and trucks as well as other grain series structures and accessories.
