Hinge Boring
Side of door drilled:
- L (left)
- R (right)
- LR (left & right)
- T (top)
- B (bottom)
- TB (top & bottom)
Note: Hinge bore code indicates hinge location as oriented from front side of door.
Hinge bore location measurements:
Hinge Drill Style:
A - Distance from the edge of door to the edge of the large hinge hole.
B - If door is drilled on the right or left, this is the distance from the top edge of the door to the center of the large hinge hole. If the door is drilled on the top or bottom, this is the distance from the left edge of the door to the center of the large hinge hole as oriented from the front of the door.
C - If door is drilled on the right or left, this is the distance from the bottom edge of the door to the center of the large hinge hole. If door is drilled on the top or bottom, this is the distance from the right edge of the door to the center of the large hinge hole a oriented from the front of the door.
Note: Hinge bore measurements are in millimeters.
Standard hinge bore measurements:
*Note:
- Under 6.75" (171mm) height of doors cannot be hinge drilled on sides.
- 6.75" (171mm) to 10" (254mm) height doors will be hinge drilled 2" from top and bottom.
- 10.01" (255mm) to 12" (305mm) height doors will be hinge drilled 2 1/2" from top and bottom.
- Over 12" (305mm) height doors will be hinge drilled 3 1/2" from top and bottom as shown.
- Screw and dowel miter doors cannot be hinge drilled less than 2 3/4" from top and bottom of door therefore the minimum height of a screw and dowel miter door that can be hinge drilled is 8 1/4" (220mm).
