[TowerTalk] 2" O.D. Pipe???

[Guy Molinari]

I found my 1026DOM masts locally.   My supplier even handled getting them hot dip galvanized for me.

 

I saved money over ordering from the usual vendors, but the big savings was the elimination of shipping costs.   Don't underestimate this.   Also, my vendor provided the engineering certificates from the steel manufacturer.

 

Hope this helps,
