GATHERING DOOR INSTALLATION: ATTACH Z-DOOR
RAIL TO SECURE DOOR TO END WALL
Required parts:
• 106936 Z-door rail and FA4484B Tek screws
Complete these steps:
1. Take one 10' section of the 106936 Z-door rail and,
beginning at ground level on one side of the door,
secure the Z-door rail to the flat plate attached to the
door jamb. Verify that the door is in the correction
position and centered. Use FA4484B Tek screws.
Verify that the finished edge of the door panel is
outside the channel created by the Z-rail. See diagram
below and photo to the right.
2. Take another Z-door rail section, cut a section to
complete the first run, and secure in place. Z-door rail
runs to the top of the installed flat plate attached to
each door jamb.
Do not install above this point.
3. Repeat the steps to attach the Z-door rail to the
remaining door jamb.
ATTENTION:
For the door to operate smoothly,
door conduits must remain loose in the Z-door rail
once it is installed. Verify that the correct clearance
is maintained and that the cables are not pinched
between the Z-door rail and the flat plate.
4. Continue by attaching the pulley assemblies.
