To ensure that the ladder is at the correct angle:
1. Place your toes against the
bottom of the ladder side rails.
2. Stand erect.
3. Extend your arms straight out.
4. The palms of your hands
should touch the top of the
rung at shoulder level.
The four-to-one ladder length
to set-back relationship
creates the safest ladder use
angle. Ladders placed either
too close or too far may tip
over at the top or slip out at
the bottom.

Place an extension ladder at a 75-½° angle. The set-back

of length (“L”) to the upper support point.
*NOTE: For a quick estimate, count
the rungs. They are spaced 12" apart.
