It took some doing to get this arm. I used to have a GTO dealer that was well stocked and knowledgeable locally but they closed up. Its near impossible to get support directly from GTO anymore. The first contact with gateopeners unlimited was unsatisfactory because they insisted i had to buy a whole gate opener box, brackets and all. I went back to the compant that GTO sold to and got the part numbers of what i actually needed. Armed with the part numbers I was able to get exactly what I needed from Gateopeners. Initial contact bad, final result good but time wasted.
