We are sorry you had a bad experience. The jig is meant to sit on the metal base plate with the arrow facing down. When its on the base plate and up against the post you place the u-bracket in the hole and screw the bracket to the post. It is only to be used for the bottom brackets as once you have those in place then you can set the panel on the brackets and slide the top u-brackets into what we call the H-channel of the railing to screw into post. We have many installation videos on our website if that helps or if you need further assistance, please give us a call at 1-844-612-2742 and one of our installation pros would be happy to help you.
