What is the minimum clearance required between the jamb and the door after the car jambs are set?

The minimum clearance required between the jamb and the door after the car jambs are set is 1/4 inch. This specification is important for several reasons.

Firstly, a clearance of 1/4 inch ensures that the door can operate smoothly without binding or sticking against the jamb during opening and closing. Adequate space helps to accommodate any slight variations in door alignment, which can occur due to settling of the building or changes in humidity.

Secondly, this clearance is necessary for safety reasons. It allows for the necessary gap to prevent entrapment of objects or fingers in the door area, minimizing the risk of injury.

Finally, following the manufacturer's specifications for clearance ensures compliance with industry standards and codes, which is critical for the safe operation of elevator systems. By maintaining this standard clearance, technicians help ensure the longevity of the door's functionality and the overall reliability of the elevator system.
