Removing door hardware from the bottom of a frame
Remove door hardware from the bottom of a NEBS 2000 frame as part of re-
deploying all of the door hardware.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• Identify the hardware in the figures
— “Orientation of a kickplate extension to the base of a NEBS 2000
frame” (page 766)
— “Orientation of lower right door hardware” (page 767)
— “Orientation of lower left door hardware” (page 768)
• You need the tools identified in the Prerequisites of “Door hardware
removal from a NEBS 2000 frame” (page 125).
• As each part is removed, thread the screws and washers back into it so
that screws of different lengths remain associated with the appropriate
part.
Procedure steps
1 Unfasten the 2 captive screws of the kickplate extension and pull it away
from the frame as far as the ground cable allows.
2 Unfasten the ground cable on the kickplate extension. Put the extension,
screw, and washer aside temporarily.
3 Reaching inside the base of the frame from the aisle, on the right side
unfasten:
• the 4 screws of the lower door catch (or lower door hinge)
• the 2 screws of the cosmetic extension filler
• the 6 screws of the lower right (or left) extension bracket
4 Repeat step 3 at the left side bottom of the frame.
