Box track is a top hung system, where the track is mounted over an opening. Door panels are outfitted with hanger assemblies that ride in the enclosed track. The track is attached to the building by brackets. These brackets give the track stability and strength and prevent the enclosed track from opening up over time. The weight of the door is supported only by the track system. A bottom guide/roller is used to stabilize the bottom of the door.
Cleaner Operation: The enclosed box track hardware is typically categorized as your standard barn door hardware. This style of an enclosed track offers a cleaner operation by shielding the track and trolleys from dust and dirt.
