WVasello, I'm not sure I understand what your question is.
If I can define a TurtleDog Stand, I'd say it's two tripods assembled using hinges, with a rigid ridge pole, often made to be portable.
A TurtleLady Stand is basically the same only primarily made of lighter material like bamboo and usually lashed together.
The metal pole came about because OldDog came up with the fence rail that can be cut in half and fitted into itself, making it more portable because it breaks down into two more or less 5' pieces.
Nearly all these TD stands use a metal pole for the ridge pole.
I think I said all that about right.
Now what was your question again?
