Untether has a wall-attached white click rail gallery hanging system that requires D rings for wall art to be hung if required. Each rail length is a 2m drop in nylon cable. The walls are painted in vivid white matt. The floors are sealed concrete. Track lighting in black runs through the centre of the ceiling with 20 moveable track lights. Dimmer switch available. Power is available on both walls. If you have more than six 3D works will need to supply extra white plinths.
