IMPORTANT - READ THIS FIRST
●Inspect stair for any damage prior to installation.
Stair is NOT to be installed while home is under construction and
used as a construction stair.
●Door angle adjustment Screw on stabilizer arm MUST be set
before climbing stair. This adjustment provides structural support
necessary for use. See page 6.
Failure to follow any or all of these
guidelines can result in damage to
the stair and will void the warranty.

Read instructions carefully and completely before beginning installation.
This stairway is for residential use only.
Maximum capacity is 350 lbs.

Installer should be experienced in the construction or modification of structural framing
supports. Improper installation can result in stair collapse and bodily injury.
Determine location of electrical lines or plumbing before cutting ceiling.

TABLE A
1. Measure ceiling height (finished floor to finished ceiling) and verify that your unit conforms to your
ceiling height in TABLE A.
2. Determine whether the chosen location allows sufficient “projection” and “landing space” for your unit.
See TABLE A and Figure 1 & 2 below.

Preparing the Opening
1. Mark out the rough opening size for your unit according to TABLE A. Note that the finished metal
trim extends about 2” beyond the rough opening when the unit is installed (Figure 3). Allow
clearance for this on all four sides.
2. Cut the rough opening through the ceiling material.
Most attic stairs will be installed parallel to the ceiling joists (Figure 4). In cases where they are installed
perpendicular to joists (Figure 5), some joists will need to be cut and tied-in to other joists with 2” x 6” or 2”
x 8” “headers”. These headers will form the box frame into which the stair will be secured.
Before cutting any joists, watch out for electrical wiring.
If your attic is constructed using trusses, DO NOT CUT CEILING JOISTS
WITHOUT CONSULTING AN ENGINEER AND OBTAINING APPROVAL.
Because of the weight of the Rainbow Attic Stair it is highly recommended
that DOUBLE HEADERS and JOIST BRACES be used for greater strength
and safety.

WARNING

1. Person in attic should have the four joist hangers and hex nuts ready.
2. Have two additional helpers below lift the stair straight up into the framed opening until the tops of the
threaded rods clear the top of the frame opening headers.
3. Starting at one end, slide a joist hanger onto the threaded rod and thread nut down until there is only
about 1/2” slack. Do not tighten fully. Turn joist hanger at a 45 degree angle to span the frame cor-
ner. Figure 6. Repeat the process until all hangers are installed. With hangers holding stair in place,
helpers can let go.
4. Square stair to frame. Try to maintain an even gap all around between stair and headers.
5. Tighten nuts in stages all around. Do not over-tighten as this may distort metal trim on ceiling side.
6. Attach door opening hook to wood dowel using (2 ) 1/2” wood screws. Figure 7.
7. Door can now be opened but DO NOT EXTEND OR STAND ON STAIR YET.
Note: Rainbow “ProTech” stairs are designed to be installed with both steel joist hangers
and lag bolts. Do not install with lag screws alone.

1. Unfold all sections as shown in Figure 9.
2. Using a straight edge, measure the distance from Point A to Point B using the back side of center
section as a guide.
3. Slide rubber bumper off stair and transfer measurement to the back side of the section, Figure 10.
Note: Measure and cut each leg separately since there may be a variation in the floor level.
4. Make 90 degree cut and replace rubber bumper.
Note: If cut line is within 1” of bottom of tread, make cut just ABOVE tread. The set screw as shown
in Figure 11 will be adjusted to correct this.

1. Extend all sections to a straight position. Stair should now rest firmly on floor with no gaps where
sections come together.
2. If there are gaps or if the stair does not reach the ground, turn the set screw (Figure 11) clockwise to
lower stair, or counter-clockwise to raise it.
Note: Be sure to adjust both sides equally, and in small increments until stair rests properly on
floor and there are no visible gaps between sections.
