# 3 - FIT TREADS & RISERS
Fit folding tread-risers and bottom risers into stringers. Start by bending a
folding tread-riser down the center fold line (Figures 3.1). HINT: put tread-
riser in the sun to warm plastic or, if very cold out, warm fold line with hair
dryer. Do not overheat plastic as it may cause discoloration. When tread-
riser is folded into a “L” shape, position the end of the tread-riser, with the
locking tabs, into the groves of the stringer (see Figure 3.2 & 3.3). Proper
positioning of the folding tread-riser is outlined by the squares ( [] ) in Figure
3.2. The holes in the stringers, within the groves, accept the locking tabs on
the ends of the tread-risers. The letter “T” represents the tread portion and
the letter “R” represents the riser portion of the tread-riser part. The tread
portion has 2 locking tabs and the riser portion 1 locking tab. These fit
appropriately into the holes in the stringer outlined in Figure 3.2 & 3.3.
Firmly press / tap tread-riser so all button lock tabs protrude through holes
in stringer and lock in place (Figure 3.6). Similarly, the next tread-riser fits
directly above the part just inserted. Repeat for all 4 tread-risers on both
sides of step stringers. Fit the single bottom risers into the bottom groove
position of the stringers. Figure 3.2 outlines the single hole in the stringer
“BR” where the locking tab on the ends of the bottom riser fit ( Figures 3.2,
3.4 & 3.5). Press firmly so the button lock tab protrudes through the hole in
the stringer and locks in place (Figure 3.6). Repeat for both bottom risers

# 4 - FIT REMAINING STRINGERS
Figure 4.2
Figure 4.1
Set remaining two stringers (L & R) on top of
installed tread-risers, top platform and bottom
risers (Figure 4.1). Stringers are in pairs - Left
(L) with Right (R) and Left with Right. Align the
button lock tabs with the holes in the two
stringers similar to Steps 2 & 3. Firmly press /
tap stringers in place with body weight or use a
small block of wood and a hammer similar to
Step 2. Make certain all tabs protrude through
the stringers and lock in place (Figure 4.2).
