Two or more sliding doors. Each door is on its own track and interacts with each of the other doors through the use of bump plates. If one door is pulled out, all subsequent doors come with the lead door until the opening is closed off. Doors must overlap each other when in closed position. This overlap is dictated by the bump plate system.
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 continous bottom guide system is recommended 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.
Track is available in stock lengths.
Adjustability: The hanger assemblies (rollers) that attach to the door and ride in the track, offers adjustability to accommodate various door thicknesses. The hanger assembly also allows for limited up/down adjustability for the door, making installation easier.
Door Weight Capacity: The enclosed box track design offers increased rigidity to the track allowing this type of sliding door hardware to accommodate heavier doors. Modern day enclosed track feature the following capacities:
- Light duty: 200-400 lb. capacity.
- Medium duty: 600-800 lb. capacity.
- Extra Heavy Duty: up to 5,000 lb. capacity
Flat Track is a top hung system, where the track is mounted above the opening. Door panels are outfitted with a pair of hangers that are assembled to specifically suite your door thickness. Only one pair of hangers is recommended per door. These hangers roll quietly on top of the flat track. The track is custom cut to length to suite each opening/application with mounting holes spaced equally or per the customer's designation. The track is offset from the wall/solid blocking using custom length wall spacers and fastened into place by either lag screws or another type of appropriate fastener. The weight of the door is supported only by the flat track system. A bottom guide/roller is used to stabilize the bottom of the door.
Standard Door Weight Capacity:
- Standard Duty: up to 400 lb capacity per door.
- Heavy Duty: up to 800 lb capacity per door.
Only one pair of bottom roller wheels are required per gate or door.
Bottom rollers are built into the frame of the door or gate and are designed to carry the entire weight of the door rolling on floor track. A top guide system is used to prevent the door from tipping over at the top.
Used for the following applications:
- The wall or ceiling is not strong enough to support the weight of the door.
- There is a limited amount of room for hardware at the top of the door.
- A header does not exist across the top of the opening. Typically true for sliding gate applications.
- Bottom rolling hardware can support much heavier doors than overhead style box and flat track hardware. Up to 128,000 lb capacity.
