Suspended sliding door is used in the production area of a factory for the following reasons :
1. Trolley, hand truck, hand pallet truck which are used to move the products will not damage the track as there is none in use.
2. There will be no extra manhour spent to clear the track of sliding door which is a dirt trap. If this is not done, the roller will get spoilt easily.
3. It doesn't take up space from the opening of the door.
