Wedge-Loc Gate HInges are designed to fit on t-posts for lightweight galvanized panel gates or tubular gates.
To hand a 10-12' gate install a brace for a corner. This will gibe your past the support it needs to swing the longer gate. A walk through gate may be hung from a single diagonal brace. Be sure to use a 7 or 8' post
Use proper eye, hand, foot and skin protection.
