WARNING
Support boards must be fastened securely to
temporarily support the weight of the ladder
when it is placed in the rough opening.
2. ATTACHING TEMPORARY SUPPORT
BOARDS:
It is necessary to temporarily support the
ladder in the prepared rough opening by using
1 x 4 x 32" boards that extend from edge to
edge across each end of the rough opening.
The boards form a ledge to support the ladder
before it is permanently secured. Care is
important in positioning the boards.
a. Secure first temporary support 3/8"
from the inside edge of Header “A” .
Header “A” is the end where the
hinge of the ladder will go.
Make sure all (3) screws penetrate
header. (See Figure D & E).
b. Measuring from the inside edge of
first temporary support, secure
second temporary support so that the
inside edge is 63-1/2" from inside
edge of the first temporary support.
(See Figure D)
c. Be certain both first and second
temporary supports are secured
firmly into respective headers.
(See Figure E).
