10.
Snap plastic post adaptor strips into post channel
(Fig. 14).
NOTE:
If installing mid-rail at 36": bottom post
adaptors are the shorter length at 27" long.
If installing mid-rail at 42": bottom post
adaptors are the longer length at 31
11.
Next, install horizontal boards (see Step 5 for
calculations on cutting infill boards if necessary):
Install (6) boards* horizontally into bottom rail
(Fig. 15).
* Depending on desired height of mid-rail
(36" or 42") you will need a different number
of boards on top and bottom.
For 36" height:
• 5 boards below mid rail
• 6 boards above mid rail
For 42" height:
• 6 boards below mid rail
• 5 boards above mid rail
NOTE:
Lightly use rubber mallet as needed to fully
nest the boards on top of each other. Boards
may need to be inserted at an angle to start for
easier installation.
12.
Install mid-rail (Fig. 16). Snap second set of post
adaptor strips into post channels above mid-rail
(Fig. 17). Insert the next (6) boards* over mid-rail.
13.
Install top rail on top of the boards, pre-drill with
a
⁄
" drill bit, and screw all three rails into place

(Fig 18). Screws should be 2" apart from each
other with bottom screw attached about
above the bottom of the rail.
NOTE:
Screw all three rails into place at both ends
of the rail through both posts. This is done by
securing two screws through the mid rail and
two screws in the top rail at each end (Fig. 19).
14.
Remove the 2" spacer blocks from under the
bottom rail.
