Topband: Irrigation verticals

["Rudy Severns" <rudys@ordata.com>]

A couple of comments on Larry's irrigation pipe vertical.

The clamp he shows on his web site is a standard item at places that sell 
the pipe.  The clamps are iron but heavily galvanized and I have never 
noticed any problem with the aluminum on my verticals.

The 4" irrigation pipe comes in two wall thickness': 0.050" and 0.070".  The 
0.070" is sometimes called "torque tube".  It is more expensive but also 
stronger.
