Step 4 – Purlins
The straight
purlin pipe
sections connect together with self-
tapping TEK screw. The assembled purlin is attached to the first
and last bow (Fig 4.1) using a 2-hole strap (Fig 4.3). The purlin
clamps are used on the remaining bows (Fig 4.4). Trim extra
pipe off. The Dakota House has 3 runs of purlin. One at the
center of bow inside of the house (Fig 4.1), one on each sidewall
at top of upright inside of the house (Fig 4.2). Make sure to view
illustrations.
NOTE:
The TEK screw is drilled through the 2-hole strap in Fig 4.3. This
secures the end of purlin to greenhouse.

Step 5 – Base Boards
Attach
base boards
(2 x 6 pressure-treated recommended) on
the bottom of the sidewall outside of house with supplied 2-hole
pipe straps.
IF you have roll-up sides you will need to install a head board
also. This is installed anywhere from 3 feet all the way up to the
bend at about 6 feet on each side. Install this with the supplied
2-hole straps.
NOTE:
You must attach 2 hole strap to ground stake using self-tapping
screws also use wood screws (not included) to attach to your
timber.
