  • Universal Mounting Channel
    Publication number: 20070247040
    Abstract: A universal mounting channel for use in an electronic equipment cabinet is provided which allows various mounting structures to be secured to the channel at various locations along the channel. The channel includes an elongate slot extending along the entire length of the channel and a number of opposed pairs of openings disposed on opposite sides of the slot. The slot allows for the mounting members to be slid along the channel while the openings allow for the mounting members to be aligned at the same position with each channel to which the rail is secured to ensure the mounting members are attached to the channels at the desired location. Each channel also includes apertures along each side of the channel to which ties or straps can be attached that secure cable bundles along the sides of the channels.
