What is the recommended gap or overlap for vertically sliding, bi-parting freight doors?

  1. 1/2 inch

  2. 3/4 inch

  3. 1 inch

  4. 1 1/2 inches

The correct answer is: 3/4 inch

The recommended overlap for vertically sliding, bi-parting freight doors is 3/4 inch. This specific measurement ensures that the doors properly align when closed, preventing any gaps that could lead to drafts, water ingress, or security issues. A 3/4 inch overlap strikes a balance between providing adequate sealing and allowing for the necessary movement of the doors without causing undue strain on the tracks or the door mechanisms. This measurement is particularly important for freight doors, which must accommodate a variety of conditions and loads, ensuring functionality while still providing the necessary clearance for operation. Other options might not offer the same level of functionality or could create issues such as excessive wear on the doors or difficulties in sealing the door space effectively.
