Find where the double fold is, and make a
large, visible mark with an ink marker to
mark the center of the covering.
Put a step ladder inside the dome. Take the
covering and put the marked center over the
top of the step ladder.
Make certain the longer part of the
covering is aligned down the length of the
tunnel dome.
Get under the covering and place the marked center of the covering over the hub at the
top of the dome. Have 3 zip ties in a daisy chain ready to cinch down the covering over
the hub. You may need one or more people to help you do this.
Lift the covering up over the hub, and
secure it to the center top hub with zip ties.
