For ladders 40 feet or longer, how much overlap is required between adjacent sections?

Explanation:
Long ladders that come in sections must overlap where the pieces meet to keep the sections secure and the rung alignment stable as you climb. For ladders 40 feet or longer, the rule requires a four-foot overlap between adjacent sections. This amount provides enough contact for the locking mechanisms to engage properly and for the load to be shared safely across the joint, reducing the risk of the sections slipping or separating under weight. A smaller overlap, like three feet, would weaken the joint, while more overlap—five or six feet—still meets safety needs but the standard specifies four feet as the minimum.
