Question: 1 / 400

If freight doors are binding because they are hanging out of square, what adjustments should be made?

Adjust door track chains

Freight doors can become binding when they are out of square, meaning that they are not properly aligned with the door frame. When this happens, they may not open or close smoothly. Option B, changing the motor, would not address the root cause of the issue. Lubricating the rails, Option C, could potentially make the doors open and close more smoothly, but would not fix the misalignment. Tightening the bolts, Option D, may help hold the door in place temporarily, but would not permanently fix the issue. Adjusting the door track chains, Option A, would properly align the doors and fix the binding issue.
