Split Mullions
• Measuring Tape • Pencil

To install Mullion in frame
1. Close and block the doors against the frame stops. Check gap between door leaves
and door to frame, and correct if necessary.
2. Locate the center of the opening on the floor. Using the bottom retainer, mark the
positions for the two drop-in fasteners.
a. The bottom of the door should come to rest against the surface of the
mullion.
b. Modify threshold as required.
3. Drill (2) 3/8" diameter holes in floor with cement bit to a minimum depth of 2-1/2".
4. Fasten bottom retainer to floor.
5. Locate the center of the opening on the top of the frame. Using the top retainer,
mark the positions for the (4) fasteners.
a. The door should evenly rest against both the frame stop and the mullion.
b. If a top retainer mounting kit is used, modify weather-stripping as required.
6. Drill and tap each location for 1/4"-20 fasteners.
7. Mount top retainer on frame with provided fasteners.
8. Assemble long mullion tube to connector using 8 1/4"-20 flat
head screws (torque to 150in-lb)
NOTE: Short mullion tube goes on top.
9. Measure distance ("Dim X")
between top of frame (where
top retainer is mounted)
and floor. Remove material
from bottom of long mullion
tube per the formula: Length
of Assembled Split Mullion
Tube = "Dim X" minus 3/4".
NOTE: This leaves approximately 1/8" clearance between the mullion and the top
retainer when mounted.
