Step 4 SETTING LADDER HEIGHT
The lower section of the ladder may require
trimming and adjusting feet to proper height.
1.
TAKING YOUR MEASUREMENT: (See Figure N)
a. With the unextended ladder in the fully
open position, measure height "Y"
from bottom of the wood frame of the
attic ladder to the floor. Refer to Table 1
before proceeding to the next step.
WARNING
The attic ladder must be adjusted to match the
proper height where it is installed. Failure to do
so may result in damage to the ladder or injury
to the user.
2. TRIMMING LOWER SECTION:
a. Remove the nylon tie holding the ladder
sections together.
b. Fold the lower section of the unit under the
middle section (See Figure O).
c. Measure the required cut off distance "X",
defined in Table 1, from the bottom of the
lower section and mark a straight line
perpendicular to rail, using a pencil and
carpenter's square. (See Figure O)
d. With ladder properly supported, use a
hacksaw to cut off excess lower section at
line marked in step c.
e. Unfold lower section of the unit to the
open position.
YOUR ATTIC LADDER HEIGHT HAS BEEN
PROPERLY SET.
