How to Install Soss Hinges

Soss hinges are known as invisible or hidden hinges that are completely mortised inside the door and frame and cannot be seen when the door is in the closed position. Hidden hinges are typically more expensive than regular door hardware and are usually used on higher-end applications. If installing Soss hinges, the frame and door must be properly prepared so the hinges can be installed correctly. Installing hidden hinges can be a little more difficult, especially if you are an inexperienced hinge installer.

Instructions

- 1
  Create a crease in the paper template provided with the door hardware on the scored line. Push a hole through the drill-point indicators on the template with a pencil.
- 2
  Position the template on the edge of the door in the location you wish to install the hinge. Use a measuring tape to figure out where to place the hinge. Typically, a door hinge is installed about 5 inches from the top of the door and about 10 inches from the bottom of the door. However, these instructions may vary by hinge manufacturer. Trace the outline of the hinge template with a pencil onto the door, so you know where to place the hinge.
- 3
  Use the template as a guide to form holes in the door with a drill equipped with bits of the proper size.
- 4
  Remove wood material left by the drill with a chisel. This is a called a mortise so the hinge can fit into the groove created in the door. Position the flat face of the chisel on the side of the hinge opening. Use a hammer to remove excess wood.
- 5
  Set one-half of the hinge into the mortise cut in the door. Insert the screws into the holes you drilled and secure with a screwdriver.
- 6
  Hold the other half of the hinge into the remaining mortise cut. Place the screws into the openings you drilled and tighten with a screwdriver.
