What should be checked regarding the finished floor before setting the sill?

Before setting the sill of a passenger elevator door, verifying the height of the finished floor is essential. This is crucial because the sill must align properly with the finished floor to ensure safe and effective operation of the elevator doors. An incorrect height can lead to operational issues, including difficulty in opening or closing the doors and potential safety hazards for passengers.

Ensuring that the height is accurate allows for a smooth transition from the floor to the elevator, helping to prevent tripping hazards and ensuring that the elevator is level with the floor of the building. Proper alignment also minimizes wear and tear on the door mechanisms over time, contributing to their longevity and functionality.

Focusing on other aspects such as texture, color, and material is less critical compared to ensuring the height is correct. While these factors can impact aesthetic choices and material compatibility, the primary concern before setting the sill is achieving the proper height to ensure a safe and functional installation.
