How to install heavy-duty piano hinges

The installation of heavy-duty piano hinges is different from the installation of normal heavy-duty hinges. It is possible that we will need at least two or more people to assist with the installation. This is because the length of heavy piano hinges is too long for one person to complete.

At this point rotate the hinges on the door and door frame, marking the location of the first and last holes. Once you are sure the positions are correct, drill the remaining holes and tighten the screws.

After installation is complete, be sure to check for any rattles or doors that do not close tightly. Otherwise, the hinges may need to be adjusted.
