The C5 end post is a great choice for use as end posts in vineyards. The built-in holes and hooks make trellis installatioin fast and easy. The rolled edges of the C5 post make it machine harvester friendly. The C5 is available in Corten, HDG and Zincor (Corten + HDG on the bottom portion of the post). The C5 post can be driven into the ground using a tractor munted pounder or a gas powered driver such as the RediDriver.
