What is the minimum overlap required for extension ladders taller than 48 feet?

The minimum overlap required for extension ladders that are taller than 48 feet is 6 feet. This specification is crucial for ensuring safety and stability when using taller ladders. The overlap refers to the length by which the sections of the ladder overlap each other when extended. A greater overlap contributes to the structural integrity and stability of the ladder while it is in use, reducing the risk of tipping or collapsing under load.

For ladders exceeding 48 feet, 6 feet of overlap helps ensure that the ladder remains securely extended, allowing users to work at heights without compromising safety. This standard is based on safety regulations and best practices in ladder design to provide adequate support. Ladders that do not meet this overlap requirement may not provide sufficient stability for safe use, especially in dynamic work environments where movement or shifts in weight can occur.
