How do I repair a broken hinge bar on a frame in the field?
Provided the frame is not fire rated and you have access to a welder, the hinge bar can be re-welded to the frame using a plug welding technique. If the frame is fire rated or you do not have access to a welder, you can use a full surface continuous hinges in place of the existing butt hinges. Most aluminum continuous hinges are UL listed/fire rated but you should confirm that the specific hinge is rated before use on a fire rated opening.
