What does #1 or #2, Yard or Wire mean?
Posts are gauged to be straight or crooked. The #1 usually means the post is straight and #2 means it can have up to a 30 degree curve in it. Most experienced fence builders know how to position the #2 in the ground to cause it to appear straight or straighter than it really is. If you have a fence line on the back of your property that few will see, it would be cost effective to use the #2 post as it is generally cheaper. Yard usually is the same as #1 – it would be of good quality to put in your yard. Wire usually means the same as #2 or it would be something to use as a line post in the pasture.
