Re: New Corners
The facia for the track can be 24" but the other side needs to be 26.5"
going along the outside. The long piece in the middle is the same as
the other ones. That is where I came up withthte 2.5 " from measuring the
existing ones.
Steve,
I don't know. I am wondering if the spec is wrong.

Hey
ed,
Did we just build them wrong or is the module specification
document
wrong?
I'd rather just build new ones.
