What must be verified after installing an elevator door?

After installing an elevator door, it's essential to verify proper alignment and operational functionality. This step is crucial to ensure that the door opens and closes smoothly and securely, aligning correctly with both the elevator car and the hoistway. Proper alignment prevents issues such as door jams, which could impede the elevator's operation or pose safety hazards to users. Additionally, checking operational functionality includes confirming that safety mechanisms such as sensors and interlocks are working correctly, preventing the door from opening when the elevator is not at a landing. This verification process is critical to maintaining the safety and reliability of the elevator system.

The other aspects, such as color, design, weight capacity, or security features, while important in their respective contexts, do not directly impact the immediate operational safety and effectiveness of the elevator door after installation.
