Use and Care Manual

Ladder labels are required by ANSI
standards to list the highest standing
level (see sample labels on p. 6).
Use these charts to determine the
right ladder length for your job:
According to the extension ladder length selection guide above, in order to access a roof 25 feet from the
ground, the minimum ladder length required would be 32 feet.
Never over-extend an extension ladder. See the following chart for ANSI (American National Standards
Institute) requirements. For minimum overlap requirements between each ladder section (base and each
fly section).
Remember, you must never stand on or above the third rung from the top of an extension
ladder, or the first step below the top cap of a stepladder.
