When troubleshooting a rolling door, it's important to gather some critical dimensions and cycle count to effectively diagnose and resolve any issues. Here are the key dimensions to consider:


Cycle Count: The number of times the door has been opened and closed. This can help determine the wear and tear on the door and its components.


Distance Between Brackets (D.B.B) or Distance Between Headplates: This refers to the horizontal distance between the inside of the bracket plates. Knowing this dimension is crucial for ensuring that the door is properly aligned and supported.


Distance Between Guides (D.B.G.): This is the least horizontal distance between guide member projections. Understanding this dimension is essential for ensuring that the door moves smoothly along the guides without any obstructions.


Guide Gap: The gap between the inner and outer guide angles. This dimension is important for ensuring that the door fits properly within the guides and operates smoothly.


Floor to bottom of bracket: This measurement is important for determining the clearance between the door and the floor, which can impact the door's functionality and safety.


Slat Length (not counting end locks): Knowing the length of the slats, excluding the end locks, is crucial for determining the overall size and fit of the door.


By collecting and discussing these critical dimensions, you can provide valuable information to your customer support team or service technician, enabling them to effectively troubleshoot and address any issues with the rolling door.
