I was going with 36x30, but I got my winter weight on


with 24 walk way no more than 20 ft long

Now…we also have some NEC clearances to the electrical portions as well we would like …care to guess what they are?

Without using a measuring tape, I like to have an arm’s length of open workspace in front of the electrical panel (and both arms width wide in front of the panel too).

Hey Ben, FedEx me one of your arms. :wink:

Speaking of arms, my brother Nick has an arm span that is longer than his height. Very unusual for human beings.

My arm span is probably longer than Nick’s height, so???:wink:

By two feet?!

WOW :shock:

That is an amazing differnence.

Just like a gorilla…sorry Nick, Ben left you open on that one.

Does he drag his knuckles?:stuck_out_tongue:
