## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Patent Application No. 61/251,429, filed on Oct. 14, 2009, the subject matter of which is incorporated by reference in its entirety.


BACKGROUND OF THE INVENTION
The present invention relates to a network cabinet fitting system. More particularly, the present invention relates to a fitting system for openings in a top cap of a network cabinet.
Typically, network cabinets have knockouts or removable openings of various sizes to allow cables to enter and exit the cabinet. When cables are run in or out of the cabinet, air within the cabinet may escape through the openings and around the cables and adversely affect the cabinet cooling systems.
Therefore, there is a need for a network cabinet fitting system that seals around cables to reduce air leaks.
SUMMARY OF THE INVENTION
A fitting system for sealing an opening in a top cap of a network cabinet. The fitting system includes a grommet and at least one of a fitting assembly and a cover. The grommet is secured to the opening in the top cap of the network cabinet. The fitting assembly and the cover are secured to the grommet and may include at least one finger lift. A sleeve or a tube may be secured to the fitting assembly.
