is used for roofs with a pitch of 4:12 - 12:12. It includes two 20" extension tubes, for a total of 51" of tube length.
The tubes attached to the top dome on you roof and the light diffuser in your ceiling are 12.5" in length. The total length of the two tubes is dependent upon the thickness of the roof deck and the thickness of the ceiling. On average, these two tubes provide for about 20" of tubing to connect to one another. If your roof deck penetration is greater than 20" from your ceiling penetration, we recommend that you purchase either a 20" extension tubes, or a 24" 0-90° to elbow (for navigating around rafters and/or other obstacles) to connect the two tubes together.
