What is the required clearance from the bottom of the car door to the sill?

The required clearance from the bottom of the car door to the sill is 1/4 inch. This specification is essential to ensure proper operation of the elevator door and to provide adequate space for the door to open and close without obstruction.

A clearance of 1/4 inch allows for slight variations in floor heights and helps prevent door damage or interference due to potential misalignments. It also contributes to safety by ensuring that the door can fully close, minimizing the risk of catching or pinching hazards. This clearance is a standard requirement in elevator installation and maintenance guidelines, emphasizing the importance of adhering to manufacturer specs and safety codes in the elevator industry.
