Piece Doors Without Track: Mark a vertical
centerline on the header above the door. Manually raise
the door to its high arc position and temporarily clamp
in that position. With the door in this high arc position,
measure the distance from the top of the door to the
floor (see figure at left). Subtract the actual door height
from the high arc distance to the floor. This is the high
arc rise of the door. Unclamp and close the door.
Using the table below, draw a horizontal line at the
appropriate height above the door to intersect with the
vertical centerline.
