CAUTION: All screws connecting the ladder to the RV must
be fastened to the RV’s blocking or sub frame. If you are
unsure about the structure location, contact your trailer
manufacturer. It is unsafe to use a ladder that is not connected
to the RV’s blocking or sub frame. Maintain safe contact with
your new ladder at all times while ascending or descending.
Be sure to use an outdoor type sealant at all points where holes
are drilled into your RV.
