STEP 1: PRELIMINARY INSTALLATION INSTRUCTIONS
- A. Attach temporary supports “A” and “B” with 2 ½” deck screws as shown in Figure 4.
Support “A” should be located at the end where the door hinge of the ladder will go. The edge of support “A” should extend into the rough opening 3/s” as shown in Figure 5. Make sure both screws penetrate header above ceiling.
-
B. Measuring from the inside edge of support “A”, locate and secure the inside edge of support “B” 52 7/s”from inside edge of support “A” (Figure 5). Make sure both screws penetrate header above ceiling.
-
C. Thread pull cord through pre-drilled hole in door and tie a knot in end of cord. Length can be adjusted after ladder is completely installed. Be sure the knot is large enough to not slip through the hole.
-
For aluminum models, remove aluminum feet on bottom section. These will be reinstalled in Step 3.
-
D. Position one person up in the attic, and position the other person in the room below. When using stepladder make sure ladder is fully open, all feet firmly supported and user’s weight and materials he is carrying does not exceed the load rating of the ladder.
-
E. The person below will need to raise the attic ladder into the rough opening and with assistance from person above position securely on the temporary support boards.(Figure 6).
CAUTION: DO NOT try and open the attic ladder door at this time. The ladder could shift and fall out of the ceiling. Wait until after completing step “F”. -
F. Make sure frame on door hinge end of ladder is pushed up against header and is centered side to side in rough opening. With the door closed, secure frame to header using two 2 1/2″ wood screws (Figure 7). Due to the tight conditions, screws will need to be installed at an angle through the frame and into the header. Do not use the pre-drilled holes for the wood screws. These holes are used in Step 2.
- G. Carefully open attic ladder door but do not unfold the climbing section until indicated in step 3. Center and square the opposite side of attic ladder frame in the rough opening using shims. Ensure ladder frame is square by measuring diagonals of the frame within 1/8″(Figure 7).
- H. secure sides of ladder frame to ceiling joists with 2 1 /2″ wood screws at shim locations (Figure 7). Do not use pre-drilled holes for wood screws. Pre-drilled holes are used in Step 2.
CAUTION: This is only a temporary connection, DO NOT climb on ladder in this condition. Wait until after completing Step 3.
STEP 2: PERMANENT INSTALLATION
- A. The ladder comes with pre-drilled holes for permanent installation at locations shown in Figure 8 for wood models and Figure 9 for aluminum models. Shim, when necessary to fill space between ladder frame and rough opening, at pre-drilled locations. Using 1/s” drill bit, drill pilot holes through shim into ceiling joists and header.
- B. Install the ten 3″ lag screws provided, at each location to permanently secure the ladder.
- C. WARNING: Never use deck or sheetrock screws in place of lag screws for permanent installation.
- D. Remove temporary boards from ceiling installed in step 1.
STEP 3: ADJUST LADDER LENGTH
Remove plastic straps holding the sections together and carefully unfold ladder to the ground rotating bottom section behind middle section (Figure 10).
WOOD MODELS ONLY:
(Aluminum models: skip to next section on page 8)
- A. Press down on top and middle sections of the ladder to ensure the power arms are fully extended before taking measurements for trimming your ladder.
- B. With a straight edge, measure distances from middle section to floor, for both A & B lengths (Figure 11 ). Record the results in the space provide in table 2. Take measurements for both the left and right rails.
- C. Complete the table: Subtract¼” from each measurement and record in table 2 in row titled “Cut Length”
- D. Transfer these dimensions to the bottom section of the ladders right and left rails and draw a cutting line between the two points. Trim bottom section to length using wood saw.
- E. Install rubber tread to bottom ends of rail using 1″ screws provided. Drill ½6″ pilot holes into wood prior to installing screws to prevent splitting of rail (Figure 12).
Proceed to “Check the length after making your cuts” on page 9 …
ALUMINUM MODELS ONLY:
- A. Using a tape measu re double check the heig ht of the ceiling.
- B. Determine the location to cut the leadder rail and ladder feet for your ceiling height. Follow table 3 and Figu re 13.
- C. Cut the side rails and ladder feet (when required) at the appropriate line. NOTE: The rail is not pre—ma rked for angle cut s.
- D. Press down on the climbing se ction to ensure that the folding a rms are fully extended.
- E. Slide aluminum foot over ladder rail as shown in Figu re 14. Position so the rubber foot is in contact
holes in rail. Attach using (2) 1/4″ bolts and se rrated nuts per side (included).
Check the length a fter making your cuts
Again, be su re the attic ladder p ower arms are fully extended. Trimmed
correctly, your attic ladder should look like Figu re 16. Verify that there
are no gaps in the se action and both feet are flat on the floor.
If the attic ladder looks like Figu re 17, then both of the legs a re too long
and need to be trimmend fu rther.
If the attic ladder looks like Figu re 15, then both of the legs a re too
short, and the attic ladder is not safe to use. A new Iower section would need
to be purchased from the manufacturer.
- F. Install weather stripping per instru ctions provided. (AL2211R5, AL2511R5, WL2211L models)
- G. To install trim molding Ie ave 3/8″ clearance between your door panel at the hinged end and 1/8″ on other 3 sides.

Recomendation for door paint
A Kilz primer coat can be applied to the door surface with a roller or brush.
This seals the door material to avoid possible water damage during painting.
Specifically, we recommend applying Kilz Brand Oil-based Original Interior
Primer to the entire door surface to ensure suitable protection and a uniform
appearance of the topcoat. The surface is ready for painting 1 hour after
application of the primer. The Kilz primer works with Alkyd, Oil and Water-
based Topcoats.
