DOOR PREPARATION
Mark the Door
Note: Accurate door preparation, including drilling throughbolt holes, is essential for proper
operation. The hand and bevel of the door affect template use. For doors already
prepped, make sure the preparation correctly matches the templates provided before
drilling throughbolt holes. If the door preparation does not match the template, redrill
the door to match the template.
To mark the door, complete the following
steps:
1. Locate and mark the horizontal and
vertical centerlines on the door at the
desired height above the floor.
2. Fold the template on the dashed line
as indicated on the template. It is
critical that the template be folded
correctly on the proper dashed
line to ensure proper hole align-
ment. Place the fold on the edge of
the door. Refer to Figure 2. The
horizontal and vertical centerlines on
the door should be clearly visible and
aligned with the centerlines provided
on the template.
For non-prepped doors:
3. Locate and mark the centerline for
the 1” (25.4mm) diameter latchbolt
hole on the door edge based upon the
door thickness and the desired height
above the floor.
4. Locate and mark the centerline for the
2 1/8” (54mm) diameter hole at the
height marked for the centerline of the
latchbolt. Refer to Figure 2.
5. Locate and mark the centerline for the
1” (25.4mm) diameter strike hole on
the door jamb at the same height as
the latchbolt hole. Refer to Figure 3.
