A strap hinge provides strong support on heavy swinging doors. Most people use this type of hinge on barn and shed doors. To install this type of hinge, here is what you should do.
Step 1 – Prepare the Door
You should install around three hinges, one on the lower part of the door, one in the middle, and one on the upper end. The hinges on the bottom and the top of the door should be around one inch from the edge of the door.
Step 2 – Drive in the Screws
Put the strap hinges against the marked areas then position the lag screws on the holes on the hinges. Use the electric drill with socket bit to drive the lag screws into the door and make sure that the hinges are securely fastened to the door.
Step 3 – Set the Door on the Frame
Put the wood plank underneath the door frame then carefully hoist the door and set it into the frame. The wood plank will help raise the door and provide clearance beneath it.
Step 4 – Install the Hinges on the Frame
Screw the other end of the strap hinges into the door frame.
