Determine whether the chosen location allows sufficient “projection” and “landing space” for your unit. See Figure 1
and 2 below and TABLE A on page 3.
* Mark out the rough opening size for your unit according
to TABLE A. Note that the finished metal trim extends
beyond the rough opening about 1 1/2” when the unit
is installed. Allow clearance for this on all four sides.
* Cut the rough opening through the ceiling material.

Framing The Opening
Warning
If your attic framing consists of prefabricated trusses, DO NOT CUT WITHOUT CONSULTING
AN ENGINEER AND OBTAINING APPROVAL.
* In framing the rough opening, one or more joists (beams) will need to be cut, depending on orientation of the ladder
(parallel or perpendicular to the joists.) In either case joists to be cut must be supported on both sides of the opening
before cutting.
* Cut and securely nail headers (blocking) of the same joist dimensions to the joists as shown in Figures 3 and 4. Be
sure to nail all cut joists to headers. When installing perpendicular to joists as in Figure 4, it is advisable to double up
the headers for more strength and rigidity.
Preparing The Stair
Attach handrails to top of stair frame as shown below using hardware provided.

Installing The Stair
* Person in attic should have steel hangers and nuts ready.
* Have two additional helpers lift stair into the opening from below until
the tops of the threaded rods clear the top of the joists.
* Slide joist hangers over rods and thread nuts down without
tightening fully. With all hangers in place, helpers can let go of stair.
See Figure 5.
* Square the stair frame to opening while maintaining an even gap all
around between frame and joists.
* Tighten nuts in stages all around but DO NOT OVER TIGHTEN as
this may distort the metal trim. Shim as necessary to keep stair
square.
* Door can now be opened from below but, DO NOT UNFOLD OR
STAND ON STAIR YET.
Warning
* There should be adequate light in the attic to work safely.
︎* Be sure the attic stair door is closed and securely latched.
* Due its weight, two additional helpers should be used to raise stair into opening.
Adjusting Stair Height
Figure 5
NOTE:
Each F Series ladder is already set up for its standard height. For example, F10 series is already
adjusted for a 10’ height, F11 for 11’ height, etc. Each model can be adjusted “higher” by 4”
except for the F11 and F12 models which can only be increased by 2”. To shorten a stair below
its standard height it will need to be cut. See details that follow.
To Lengthen Stair
* First, unfold stair to ground. See operating instructions on page 8.
* Lock sections together with latch. See Figure 6.
* Loosen the 4 height adjustment nuts on plate under ladder section and pull stair assembly down until it is fully flat
on the ground. See Figure 7
* Re-tighten height adjustment nuts."
Figure 6
Note:
Models F8 to F12 have
only one section latch.
Models F13 to F15 have two.

Adjusting Stair Height - continued
To Shorten (Cut) Stair
* Using a straight-edge, measure on the front side of the stair from point “A” to floor. Figure 8.
* Transfer measurement to front side of last section and make cut at the same angle as bottom foot so it will rest flat
on floor. Figure 9.
* Remove black plastic floor bumpers on cut leg and re-install on stair.

Operating The Stair
* Using pole provided, hook into latch on face of door and pull to disengage. Pull door all the way down until it stops.
* Stand back from stair and Insert hook into ring under the bottom tread.
* Pull slowly until the bottom tread can be reached by hand.
* Lower stair to the ground and lock the section latches.
May 2020
To Open Stair
* Unlock the section latches.
* Grab bottom section of stair and lift to begin folding the ladder.
* When high enough, hook into ring on bottm step with pole and continue to lift and guide stair until fully folded on
the door.
* Hook into latch on door with pole and push door all the way up until door latch engages and is secure.

Maintenance and Periodic Inspections
The Rainbow attic ladders require very little maintenance.
It is nevertheless advisable to periodically check for proper functioning by visually inspecting the main parts and
devices. Under normal use, please follow the maintenance plan indicated in the table below.
Note: For more frequent or heavy use of the ladder, such as in commercial applications, it is recommended
that all periodic maintenance / inspection items be performed on a regular, three month basis.
