Raise the flex tube material up to the dome assembly so you
can see the aluminium retaining ring. (fig. 5)
Step 6
Using the lower edge of the retaining ring as a guide, cut the
material all the way around to separate it from the dome assembly. (fig. 6) Try to make the cut as smooth as possible.
Step 7
Expose the spiral wire, and using the tin snips, cut the wire away
as close to the edge as shown. (fig. 8)

Assemble the straight tube lengths
The Rigid Tube Kit comes with three 2 ft straight extension tubes. When installed with the Upper and Lower Elbows a
7.5 ft. total length may be achieved in most cases. You will need to measure the distance from the edge of the flange
at the dome opening, down to the top of the Diffuser Housing to find the total length. If your installation requires more
distance, you can order additional straight tubes on our website: www.ussunlight.com

Step 9
After determining how many straight tubes you require, you
will need to assemble them as follows: There should be scribe
marks on both sides of the outer surface where the double stick
tape is applied. (ill. a) If not, use a pen to mark the locations at
1 inch and 3/8 inch as shown in (fig. 10 & 11) then peel off the
backing tape. (fig. 12)
Step 10
Before continuing, cut a piece of the 2” foil tape about 24” in
length and have it nearby. (fig. 13) Turn the flat sheet on its
back (reflective surface up) and peel away about 2-3” of the
protective film on the side opposite the double sided tape.
Then form a cylinder and secure the first side at 3/8” (fig. 14)
Use the other hand to steady the cylinder in the center.
Then secure the other side at 1”. (fig. 15) IMPORTANT:
Firmly press on both sides (inside and out) of the entire
length of the tube to secure the double stick tape.
Now immediately apply the foil tape along the outside edge
down the entire length. (fig. 16) Press firmly in place up and
down the length to secure. (fig. 17)
Repeat step 10 for other tubes if necessary.
Line up the far edge (3/8”)
and press to hold.
