ladder bars?

I'm looking for a real short pair, the smallest ones I've found are 33 inches long. I was wondering if anyone knew about others that were shorter. With out having to make my own.

 

When I was looking for some that seemed to be about the shortest I found.

 

If you want shorter than that, go to a 4 bar setup.

 

yeah, go to four bars then you might find some.
oh, thats not right.
