What is the function of stops on an extension ladder?

The function of stops on an extension ladder is primarily to prevent overextension. These stops are designed to limit how far the fly sections of the ladder can extend beyond the base section. This is crucial for maintaining the integrity and stability of the ladder while in use, as extending it too far could lead to a higher risk of collapse or failure, especially under weight or stress.

By preventing overextension, the stops help ensure that the ladder is used safely and effectively, maintaining a safe angle and distribution of weight. This safety measure is essential for protecting the firefighters who rely on the ladder during operations, allowing them to work confidently from a secure position.
