Dana Dolly Portable Aluminum Pipe Kit (6-Pack, 39")

This set is for the Dana Dolly and would also work with the Proaim Polaris dolly. We are not aware of a curved option.

This kit comes with six 39" lengths of schedule 80 aluminum pipe. That would give you 117 inches for each side of the dolly track, which is just a bit under 10 feet of length.

Yes. Perfectly

Yes, you can combine two kits.

Dana Dolly make two types of track ends, the “Original” which only works with 1.25” speedrail (pipe has an O.D. of 1.66”, I don’t know where they get the 1.25” BTW) and the “Universal” which works with any size pipe from 1.25” to 1.5” (again, the pipe size does not correlate to the actual size of the pipe for some reason). The pipe kit is made from schedule 80 aluminum pipe that is 1.25” (the 1.66” O.D.) and it works with both track ends. It is a little confusing because of the fact that the actual measurements don’t correlate with what the pipe is named, but we’ve found on the West Coast people generally use the 1.25” speedrail or aluminum pipe for grip trucks, and on the East Coast the 1.5” pipe is the most common size. The Universal track ends are also the ones anyone outside of the USA will want to use. Hard to find the proper size in say, Romania.

It's not 1.25", the outside pipe diameter is actually 1.60"

the pipes have a thread cut inside, then they machined nipples with 2 male threads on them to join the tubes. you keep the nipple mounted on one side, and there is a protective rubber cap for when not in use.they are awesome for when you need to be moving around location, rather than dragging long pipe around.the threads are a little fine, be careful getting them started so you don't strip them.

I wouldn't do more then two.
