Which of the following statements is true about properly installed gibs?

Properly installed gibs are essential components in elevator systems, particularly in the context of door and entrance installations. When gibs are installed correctly, they provide a small amount of friction that is crucial for the smooth operation of the doors. This minimal friction ensures that the doors close securely and maintain their alignment within the track, preventing unintended gaps or misalignment that could lead to operational issues or safety hazards.

A small amount of friction is beneficial as it helps to stabilize the door during operation and prevents it from moving too freely. Excessive friction, on the other hand, can hinder the opening and closing of the doors, causing undue wear and potential malfunction. Regular inspection is important to ensure that gibs maintain the appropriate level of functionality, but they do not need to be replaced frequently under normal operating conditions.

This emphasizes the importance of proper installation and maintenance of gibs in ensuring both the reliable performance of elevator doors and the safety of passengers.
