HI Rich,
The trick is to open them up *sideways*. If you can, clamp the long
dimension in a bench vise, horizontally, held below the center line. Then
use a "crescent" wrench or a large pair of pliers to twist the other side
until it is as open as you need. The less you open, the less damage you'll
do to the galvanizing.
You can do the same thing in the field with two large wrenches, but you
usually need three or four hands...;-)
Have fun.
