What feature on a ladder prevents it from overextending?

The feature on a ladder that prevents it from overextending is known as the stops. The stops are designed to limit how far the sections of the ladder can slide beyond each other, ensuring that the ladder remains within a safe and functional range. This is critical for maintaining safety and stability while the ladder is in use.

By providing a mechanical barrier, the stops help prevent the ladder from extending too far, which could lead to instability or failure during operation. This function is especially important when firefighters are using ladders in high-risk environments, where a secure and reliable ladder setup can make all the difference in emergency situations.

Understanding how the stops work can help firefighters ensure they are setting up their equipment correctly and safely, which is essential for both their own safety and the safety of others they may be assisting during a fire or rescue operation.
