Question: 1 / 400

What is the maximum leading edges for center opening doors?

¼ inch

½ inch

1 inch

The maximum leading edge dimension for center-opening doors is typically ¼ inch. This specification is important for ensuring that the doors operate safely and efficiently, minimizing the risk of injury during operation. Having a trimmed edge of ¼ inch is a design standard that helps prevent pinch points and promotes smoother and safer operation as the doors open and close. It is crucial in maintaining code compliance and ensuring that the doors function properly with minimal wear and tear, which is vital in high-traffic environments like elevators.

Larger dimensions, such as ½ inch, 1 inch, or 1 ½ inch, would likely lead to increased safety hazards and operational issues, which is why they are not considered acceptable for leading edges of center-opening doors. Standards are set to protect users and to ensure longevity and reliability of the elevator system.
