What is the minimum clearance required for interlocks on freight doors?

  1. No clearance needed

  2. At least 1/2 inch

  3. At least 1 inch

  4. At least 1/4 inch

The correct answer is: At least 1/2 inch

The minimum clearance required for interlocks on freight doors is at least 1/2 inch. This clearance is essential to ensure that the interlocks function properly, allowing for safe operation of the doors. If there is insufficient clearance, it could lead to misalignment or binding, which might prevent the interlocks from engaging correctly. Proper clearance ensures that the doors can open and close smoothly while providing security and safety features that prevent accidental opening or closing during transit. Overall, maintaining this specified minimum clearance is crucial for the reliability and efficiency of the freight door system.
