Question: 1 / 400

If car doors are dragging in the sill, how high should the car doors be above the sill to prevent this issue?

1/4 inch

To prevent car doors from dragging in the sill, it is crucial to maintain an appropriate clearance above the sill. A clearance of 1/4 inch is often considered ideal for allowing sufficient space while ensuring that the doors close securely without obstructing movement. This height helps in managing any potential obstructions that might arise due to manufacturing tolerances or slight shifts in the elevator system. A gap of 1/4 inch offers a balance of functionality and durability.

In contrast, other options might not provide the optimal solution. For instance, both 1/8 inch and larger clearances like 1/2 inch or 3/4 inch could either be insufficient to prevent dragging or lead to excessive gaps that can compromise the door’s operation, security, or appearance. Therefore, a clearance of 1/4 inch is the most appropriate choice for preventing car doors from dragging in the sill effectively.
