All Colorspan downpipes are made with a taper to allow you to fit two or more pipes together.  There may be some variation within the tolerance of the taper.

Colorspan downpipes are 100mm x 50mm and 90mm round.

To fit downpipe together, follow these steps:

1. Identify the “big end” from the “small end” on each downpipe
2. Line up the “small end” with the “big end” of the two pipes
3. Align the seams of both downpipes and place your thumb over the leading edge seam on the “small end”
4. Feed the edge opposite the seam into the “big end”
5. As you lift the downpipe press your thumb into the seam to slightly distort the pipe and push into “big end”
6. Then slide downpipes over each other in a smooth action
