For ladders up to 36 feet in length, how far must adjacent sections overlap?

• A. 2 feet
• B. 3 feet
• C. 4 feet
• D. 5 feet

Answer: (B)

Ladders built from multiple sections rely on adequate contact between the sections to stay locked together and carry the weight without shifting. The overlap between adjacent sections is what keeps the ladder rigid and prevents the sections from pulling apart when you step on it or apply force while working.

For ladders up to 36 feet, the required overlap is three feet. This length provides enough engagement for the locking mechanisms and sufficient load transfer between sections, keeping the ladder stable as you climb. Overlapping less than that would weaken the connection and increase the risk of slipping or misalignment, while this three-foot standard balances safety with practicality for that ladder size.
