[RE-wrenches] Ironridge BOSS splice

[Jason Szumlanski]

That's how I read it. They meant to write:

"UFO and Bonding Hardware must be installed *no less than *1" away from the
point where two Rails join together."

It's frustrating when using 41.5" W modules on 168" IronRidge rails. Four
panels just barely fit on one rail, so when splicing for more modules you
need to cut some rail off.
