Domed Turtle Shade: 4, 2.25, OP

The measurement from the door edge to the center of the bore hole. Most latchbolt backsets are 2-3/8” or 2-3/4”.

The direction the door swings. Handing is always determined from the exterior or “outside” of the door (for example: porch to entry, hallway to bedroom, bedroom to closet). When facing the exterior of the door, whichever side the hinges are on will determine the desired handing. If the hinges are on the left, choose Left handing. If the hinges are on the right, choose Right handing.
